my first data pack so far , to enjoy the boss download my texture pack for it.
here are all of its attacks:

boss attacks:
1. main - melee swing with arms that deals from 0.5 hearts to 3 hearts.
2. attack 1 - the golem summons 4 of its minions that give it strength and speed for a couple seconds for the cost of a bit of the golems health.
dodge: this attack can be easily dodged by backing out when the boss summons the bats

3. attack 2 - the boss lifts up 2 sculk blocks off the ground and make it explosive , after 5 seconds the sculk blocks fall down and explode dealing the damage of a charged creeper. also the golem DOES NOT take damage from the explosion.
dodge: this attack is also easy to dodge - pearl away and you wont take any damage.
4. attack 3 - the boss summons an allay above its head , which summons 15 lightning bolts at you , this is the only ranged attack that the golem has.
tip: do not heal your armor when the allay is activated because all your xp will burn from the fire
dodge: this attack is not possible to dodge so you'll have to tank it
5. power up - power up is the golems only ability , the golem gets insane strength and speed for a couple seconds , i made this attack very easy to dodge but if you dont you'll pop 3-4 totems in the span of 2 seconds.
dodge: pearl away
tip: shoot the golem while its going up
