Vaal Molten Shell is a vaal spell that temporarily grants the player extra armour and causes them to deal a burst of fire damage for each physical hit they take.

Skill functions and interactions

• Duration: Skill duration modifiers will increase the duration of Vaal Molten Shell.

• Critical Strike Chance: Vaal Molten Shell's chance to crit is decided when the user initially casts the spell. It uses the user's crit chance to determine if all Vaal Molten Shell procs will crit or not crit. This means that the spell will either crit for every proc of the duration or none of them, making a Diamond FlaskDiamond FlaskLasts 4.00 Seconds

This will happen both ways (when Vaal Molten Shell is casted while Molten Shell is active). This makes it unfavorable to use both skills in conjunction with one another.

Strategy

Unlike its non-Vaal counterpart, Vaal Molten Shell will persist for the full duration, regardless of how many times an explosion is triggered. This unique property offers potentially vastly more utility than Molten Shell at the cost of less availability. Because of this, it is recommended that Vaal Molten Shell be saved for an occasion in which it will offer the greatest benefit, such as during an encounter with a unique monster or even a troublesome rare.

Due to the nature of Vaal Molten Shell, it has synergy with support gems that utilize the potentially frequent explosions, such as stun or life leech; however, the rather steep soul cost of Vaal Molten Shell gates the strength of the gem. In addition, while the armour offered during Vaal Molten Shell's duration is first-rate, it may cause conflicts with Cast when Damage Taken SupportCast when Damage Taken SupportSupport, Spell, Trigger

1.1.0d	Vaal Skill soul counts were initially balanced for Merciless difficulty, where there are more monsters. We want them to be easier to use in Normal and Cruel difficulty.

In Merciless difficulty, they require 100% more (which is the same as before the patch).
