[BUG] - Lich Eldritch Empowerment

Skill states spending energy shield on spells does not interrupt recharge, however recharge is being interrupted by casting.

Update: I just realized this is a bugged interaction with Event Horizon. Please fix this combination to work properly.

Eldritch Empowerment adds an Energy Shield cost to your non-channelling spells, which does not interrupt Recharge. Event Horizon does not add a cost to your spells, it makes you lose energy shield when you cast a spell. The description for Energy Shield explicitly states that losing Energy Shield will interrupt Recharge.

I made the same error in trying Event Horizon to disastrous results but it is 100% functioning as intended as described by in-game tooltips. It's not a bug, just a nonbo.

I'd have to say I disagree. Eldritch Empowerment says "Spending energy shield does not interrupt recharge". Event Horizon causes you to lose energy shield when you use a skill. That's a cost, you're spending energy shield when you cast.

The clear design intent here is to allow liches to spend energy shield on chaos spells to improve their damage, and I don't believe this interaction is working as intended.

So unless someone from GGG responds to this thread saying it IS working as intended, I'm going to classify it as a bug.
