General Gravicius in cruel mode

General Gravicius in cruel difficulty has several problems that you may or may not want to address. I will list them below along with the character class and style i am playing with

Character class - Duelist with dual 1 hand swords and a passive build to match. During the fight i use Flicker Strike to get close to him, Grace for extra evasion, Molten Shell to absorb damage, and Dual Strike to deal damage.

Problems

1. His molten shell is a 1 hit kill to all melee characters within range of the explosion.
2. He has no range limit on his skills so even is he is way off the screen chasing you he can still hit you.
3. His molten shell is always active even if you do not see the skill around his body. If you hit him at any time with or without the skill glow he explodes and you die.


I do not have a ranged character to attempt to fight him with on this difficulty so i can't say if the same problems would occur against them but against melee characters he appears to be bugged. They can't get close enough to him to fight because of the constant molten shell and endless mana he appears to have.

A possible solution to this would be to give him a mana limit for using those skills. Once his mana is depleted he can only use normal attacks from that point on.
