Changes to olm's auto attacks (mage/range) being predictable,
the amount of times you have to eat in olm (especially in challenge modes) and has potential to ruin your run just because of olms auto attack rng is not fun to deal with.
in solos its usually not a big deal because you will avoid most of its auto attack anyway but would improve the quality of raid, it's just more of a problem in teams.
Possible changes that could help is having a visual cue of what style olm's next auto attack will do is one.
The other suggestion would be to have the same visual queue mentioned above or without, and for the phases to do specific styled attacks.(excluding the special type of autos, flame wall, falling crystals etc.)
Flame phase: Mage only on autos (visual cues can be un necessary here)
Crystal phase: Range only on autos (visual cues can be un necessary here)
Acid Phase: Basically jads, alternating every auto or after a certain amount of autos maybe 2-3 (visual cues would be good for this probably)
Final Phase: Same as acid or have a visual indicator before its attack.
Thank you for coming to my dying at CM olm because olm hit me with the 40s x5 rng attacks OSRSTalk.
