Brave Frontier: Savage Lion (Hard Mode)

Welcome back ladies and gents. This event is part of our 6th Year Anniversary. Savage Lion has 2 parts. The first dungeon grants you Omni Tilith who IMO is busted due to her kit. She is not a replacement for QT, but creates a crazy dynamic if placed on the same squad. Hard mode is where you need to get the necessary mat for Tilith's sphere. I went through it pretty quickly so I will state what I can remember. Phase 1 - He will regenerate his HP the first few turns of the battle. At some point he will deploy a shield. The goal is to break the shield as quickly as possible. At some point, he is regeneration will stop. Phase 2 - Once you get his HP to 0, he will mention something about his defenses have been broken. At that point he will completely heal himself. This phase is pretty easy. Phase 3 - This is where things get tricky. He has the ability to literally pierce through any mitigation that is up. I cant remember the exact threshold or turn. If your unit has 99k HP, it will be one-shotted. You must have good to great OD fill. You must also bring units with revive and mitigation. He will eventually turn skip units between phases 2-3. He managed to kill my units after a full revive on the very next turn. Don't worry. The right units will take him down.
