[FIXED] Explosive affix spawn location on giant bosses

[Grazzia]

Bug description: Wrath of Azshara can spawn exp orbs into the middle of himself, he should only spawn it around himself, so the area where players are and where they can actually do something about them.

Bug desc: Helya, well on this boss, the affix is kinda non-existent, they spawn right into the middle of Helya and fall down instantly on spawn. It should put orbs to the boat, so on places where players are actually able to deal with them.

Bug desc: L'ura can summon orbs into herself when she is in its imunne phase so the orbs are unreachable because boss pushes you back if you attempt to go close. Orbs should spawn only to places where its reachable.
