What is your suggestion?:
To put Verzik's hitbox where it belongs, instead of being shifted 2-3 tiles southwest.
Is this in OSRS?:
Most definitely, yes.
Has this suggestion been accepted already?:
At least not recently, but I believe the issue has been around for a long time.
How would this benefit Alora?:
It will allow more than 2 players to melee in hard mode, without having to "crash" each others tiles/sides since the south and west side hitbox is placed underneath the boss itself. This affects Phase 2 severely as she becomes visually bigger, but keeps her small/shifted hitbox. The nylo spawns are still the same, which makes them able to spawn ontop of you.
Right now there are three options:
1. Stand on the northeastern side and risk getting explosive nylos spawned on you.
2. Stand on the southwestern side and have no idea what attack Verzik uses unless you're looking at your teammates. (Poison splats can also become invisible if placed underneath her)
3. Range/mage, which reduces DPS by a lot.
I know that melee is and should be a "high risk, high reward" attack style, which it already is with the lack of mage defense and poison splats lasting for 4 attacks on the tiles (usually) closest to her.
Will it make ToB Hard Mode easier? In a way, yes. Just less RNG dependent, but a more smooth/consistent experience.
