Lightning Wall, Lightning Rush & Orb Runemaster Build Guide

Kelvin was an unstable character, with somewhat of an explosive temper.

This build guide is to help people understand the build and its functionality. There's a good chance you could make your own variation using a similar setup.

Gameplay Style

Kelvin is a simple to run Runemaster, with minimal button manipulation. However, do not confuse simple, with not versatile. As per usual, I try to make guides for those with physical disabilities, so the cycle of skills is simple and can be ran with a 3 button mouse. He is built with maximum critical strike chance in mind and VERY high critical strike multipliers; making mundane skills hit extremally hard.

We have armed our Frost Wall to be lightning base with the Crackling Barrier node. We have also made the wall use our Lightning Blast, and have turned the wall into a bomb with Runic Conclusion. We also have converted our Flame Rush into lightning and with this, we automate Static Orb with the Beta Decay node. This causes 4 smaller orbs (Scatter Blast) as well as the primary orb to circle us causing explosions and tendrils from our highly scaled lightning damage.

We also generate significant amounts of ward via The Invoker's Static Touch, our armors PrefixPenetration with Lightning Invocations, Unsealed Mana, and Arcane Focus. Since all of our attacks have a significant chance to shock, this will build up plenty of ward to have a strong defensive lineup.

As always, my builds never require LP to function, but the build can be improved if found. (This build requires no uniques however.)

Pros & Cons


Disability Friendly (3 button mouse)

Visually exciting

Very fun and engaging gameplay

No Uniques

Excellent Clear


MUST gear to be in the 90% Critical Strike Chance

Good idols required for pushing into late game (250+)

Gameplay / Mechanics

Mechanical Function

Lightning is or only element we care about, keep this in mind when gearing. Our Frost Wall and Flame Rush will clear just about any kind of pack you run into. There may be a few enemies that will require a few shots with Lightning Blast. Bigger ones can be drop by using our Runic Invocation's Ball Lightning. From time to time you may want to pop off a dispersed pack of ranged enemies with Sea of Sparks. You can do this easily with two casts of Lightning Blast or a well timed release of Flame Rush. Frankly any one of your skills used twice (besides the channeled Flame Rush) can be done to trigger Sea of Sparks.

Defensively, we rely on our offense to generate significant amounts of ward. Which, may I add, is a lot. We utilize Frost Wall to trigger our Flame Ward which will give us 800+ ward. This can stack several times so keep this in mind when charging a ward battery. If you are lucky enough to find boots with PrefixExperimental Ward Gained on Traversal, this number for our ward will grow exponentially higher (considering our traversal skill is our damage skill).

Mana could become a problem if you are casting Runic Invocation needlessly or spamming your Frost Wall continuously for no good reason. However, the 2-4 Seconds cycle depending on our SuffixIncreased Cooldown Recovery Speed we have acquired, is the standard skill set and you should have plenty of mana to deal with this combo.

Reaching 300 mana is very important in our build. Keep this in mind. The average roles of the gear provided put us well above this threshold, however the minimum roles will not be enough. Just be sure to pay attention to this, as our Adorned Arcane Idol's depend on it to capitalize on the SuffixIncreased Lightning Damage (Doubled If You Have Over 300 Max Mana). The PrefixIncreased Lightning Damage while you have Lightning Aegis is already taken care of by our Static Armor node in Static Orb.

Defensive Mechanics

There is nothing special happening here. Most of our defenses are automated with our attacks. Our gear in our Bronze Belt, Arcane Regalia, and Arcane Visage are rolled with SuffixArmour and Reduced Bonus Damage from Crits. Getting slightly better than the minimum T-5 Roles will give us 100% reduced bonus damage taken from critical strikes, our ward will take care of the rest. However, it is still good practice to manually dodge high damage mechanics. Even though you will have enough ward to tank most damage, this should not be a habit you practice, especially if you plan on pushing into deeper corruption. Our resistances should be capped and decent roles on our blessings should take significant strain off our gear roles. With average roles (mid) you will almost be capped across the board. It is on you to find the right roles to cap this resistance. You can choose to use 1 of the 4 Small Lagonian Idol we have in the build to replace with resistances where needed (if needed). However, the gear/idols in the build are the optimal ones you can have. We also will almost always have Lightning Aegis on as well, this will give us a 25% Damage Reduction value. We should have it for (4) seconds after casting Flame Rush because it casts Static Orb with Static Armor.

Basic Engagement

Almost all of our fights will start and end the same way. Start the area by walking through a Frost Wall, and use Lightning Blast twice in order to put all 3 Gon runes on. This will start to charge our ward battery from PrefixPenetration with Lightning Invocations. Find a target and put Frost Wall between you and them. Cast Flame Rush into them, releasing the cast once you have cleared the wall. This will cause the Frost Wall to explode via Runic Conclusion and our Flame Rush will have a significantly larger blast radius with Blazeborn and Gas Powered. Pick off any trash with Lightning Blast.

Difficult Engagement / Bossing

Follow a similar approach as before, although here we are using our un-scaled Runic Invocation to cast Ball Lightning on top of the boss. Be aware of there movements, as you may waste the cast if your not paying attention. Be sure to instantly cast Lightning Blast at least 3 times to get your rune back to push up your ward battery. Rinse and repeat,



Stat Priorities


Try to stick to this as much as possible. Although some values in resistances can be swapped. Just remember, we need 300 mana and 60 intelligence.


Idols should be used to capitalize our damage, however, in the shortfall of defenses... we can use them to fill in some blanks.


These are optimal in order to minimize the strain on our gear.

Ending the Storm
Reign of Dragons
The Age of Winter
Fall of the Outcasts


The Stolen Lance


Blood, Frost, and Death


Fall of the Empire


The Last Ruin


Build Variants


Kelvin CAN be leveled with. Late game push will require more gear/idols, but level 100 echo's will be fine for him.


Farming double exalts would be the goal here. Don't forget to check the dungeon daily rewards to hunt down top tier gear found here.

Loot Filter

A good generic late game loot filter for double exalts and T7's can be found here. ONLY use this to filter out 99% of gear. Not recommended until you are mostly geared to the teeth.
