Sea of Souls
Shield of Caustic Diffusion
Heavy shield made from a dragon egg
Daily power(move): You must currently have temporary hit point to use this power. Spend a healing surge for every party member you wish to effect (including yourself). Lose all temporary hit points you currently possess and you may no longer gain temporary hit points this encounter from any source other than this power. All targeted party members gain temporary hit points equal to what you have just lost in the form an acidic secretion until the end of your next turn. This covering takes damage as normal and deals damage back to melee attackers equal to the number of temporary hit points that are lost. While the covering remains reduce all acid damage taken by half. Sustain this effect as a minor action.
