This addon is part of Angel Tale's functionality!

The original Cataclysm Apotheosis Addon had many critical issues, and was particularly difficult to balance for MODPACK players. It also had many unnecessary features that many people did not want, so we created this NEO version. We do not plan to add any features other than boss buffs. (Please exercise extreme caution when adjusting boss stats in L_ender's cataclysm config.)
To mitigate the issue of being unable to defeat bosses, we have set Goety, a balanced magic MOD, as a required dependency. (Of course, you can also use Iron's Spell Book.)

The function of this add-on for L_ender's cataclysm is to greatly buff bosses. L_ender's cataclysm is normally designed to be fought with vanilla gear, so it may be too easy with modified gear. Unlike the old version, this add-on also buffs AI speed, making it difficult even with high mobility builds.
Tip: I recommend equipping at least one Unholy Robe accessory during boss battles.
