Rogue Legacy 2 - NG+100 - Irad Prime - Full House Rules - All Burdens

I think this is the hardest Boss to do with full burdens. He is not necessarily the hardest prime boss in general, but the burdens have the biggest effect on this boss.

Irad is a very hectic boss due to the bullet hell nature, higher aggression and bullet speed make this very difficult.

Phase 1 is pretty tame, there is only one eye that does one move after another, as long as I do no mistakes I should be fine.

Phase 2 is by far the most difficult to figure out, he summons a lot of adds that are a total nightmare to control, I tried out many different strategies. I ended up with a freeze strike strategy where I try to get as many enemies as possible frozen in one spot. Before they break I hit them with the wand to apply mana leech and immediately freeze them again. Mana leech will allow me to keep enough mana to keep them frozen. Freeze strike also destroys projectiles which is very useful, especially since casting freeze strike doesn't affect your movement like other spells that destroy projectiles.

Phase 3 is tough but a lot easier to control than phase 2. Since I have a lot of vault and dash runes I can easily retreat to the left side. Since there are 3 eyes I can have a lot of mana leech allowing me to destroy a lot of projectiles with freeze strike. A huge problem was that I didn't have much opportunity to practice phase 3 and 4 as I really struggled getting past phase 2.

Phase 4 is similar to phase 3 but I can't retreat to the left, making it a lot harder. In this phase I also can have a lot of mana leech, I used freeze strike a lot at the start of the fight. Later I got a bit more confident and used tesla spike, otherwise the fight would have been too long. I got hit once, but luckily I managed to surive the rest of the fight.
