Out of the most common cookie-cutters, Prismatic Bolt Embermages involve the most strategy. Prismatic Bolt is an auto-aim multiattack skill, that alone doesn't involve any tactics or thinking, but playing this build as it is intended requires two additional skills.Ice Prison
Ice Prison is one of the most powerful crowd control, obviously. It is less obvious, that it can easily outDPS most other embermage skills. Of course, it's most important trait is the utility it gives.
- Crowd Control
Ice Prison places 10 icy pillars in a circle. It stops enemies, but is passable for allies. You can use it as a safe room, a roadblock, a prison, or a wall to block ranged attacks.
Ice Prison deals possibly the highest burst damage in the arsenal of the embermage.
After tier1, Ice Prison deals damage when shattering. It's base damage at lvl100 is estimated around lvl2373 per pillar, which translates to 23730, higher than the maximum damage of the 3 Brand skills together. You can trigger shatter on will for an outrageous damage with casting Ice Prison again.
After tier2, Ice Prison deals non-stacking ice damage over time to nearby enemies. While this damage is inferior to the shatter damage, it's always welcome. Enemies have no artificial intelligence set up for avoiding Ice Prison, weaker foes often die to the damage over time effect alone.
After tier3, Ice Prison's cooldown is reduced to 2 seconds, making it possible to shatter it every 2 seconds for the previously mentioned semi-phenomenal, nearly cosmic damage.
Thunder Locus is one of the key skills of the successful endgame embermage. Thunder Locus can deal with some of the most dangerous foes or can kill off the weaker ones before they have a chance to retaliate.
- Spawn Camping
Thunder Locus's unique trait is the ability to target otherwise untargetable enemies. Most enemies are very likely to die instantly while they spawn if they are hit by a Thunder Locus of a well-geared embermage.
Thunder Locus has a very long duration, it is possible to place it ahead and lure enemies through it. Otherwise dangerous spellcasting and ranged enemies are die easily if they are lured in the range of the spell. Enemies have no artificial intelligence set up for avoiding Thunder Locus in any way.
Bossfights with the Prismatic Bolt Embermage are quite straightforward, spam Prismatic Bolt until elemental debuffs apply, after that just keep them on the boss and try to deal some damage to it every second.
Managing this is actually quite easy with extensive extensive use of Ice Prison, especially when it is combined by Thunder Locus. While Ice Prison easily shatters to boss attacks, you can recast it every 2 seconds, buying time to cast more Prismatic Bolts.Ice Prison
In bossfights it's both your only crowd control and one of your heaviest nukes, as it is already mentioned. It's heavy ice damage can reset the timer on Frozen debuff as well.Thunder Locus
In bossfight it's a way to deal periodical damage to the boss, triggering already applied Brand skills without actually attacking the boss. It's good lightning damage may help keeping the Shocked debuff on the boss.Hailstorm&Firestorm
If the player also has Hailstorm and/or Firestorm, it becomes a lot more complicated, but also a lot more effective, the Prismatic Bolt Embermage enters a "rotation" to maximize damage done.
Opening: Ice Prison => Thunder Locus => Prismatic Bolt until elemental status effects are applied
Loop: Ice Prison => Hailstorm => Ice Prison => Firestorm, rinse and repeat
As you can see, Prismatic Bolt is not part of the rotation in bossfights, it's just an opener in this case. On the other hand, If the player fails to control the fight, the player must change tactics, spamming Prismatic Bolt and Frost Phase to dodge and attack.
