Invasion Code Red Reborn(Illager Boss)
In raids, a configurable chance brings a raider boss called the gashslit, which Invasion Code Red Reborn adds for Forge.
What it does
The gashslit is a boss mob that can appear during raids, and the chance of that happening is set in the config. It has 680 HP, scaled by a factor of 340, and its hits land for 13 to 24 damage depending on which attack it uses. As its remaining health drops, its defense and attack damage rise, and at 40% HP or less it shifts into a second phase with new attacks and greater damage and reach.
Its moves include a melee attack that gives it a very brief burst of Speed level 10 afterward, a ranged sword energy shot, a charge that rushes at the target for at least 46 damage, and a summon that calls several Riftblade King Dragons into the fight. The mod is for Forge and covers 1.20.1 – 1.20.6, with 2.0 for 1.20.6 as the latest file. It runs on client and server, so both sides need it, and it is released under All rights reserved, which means it is not open source.
