I just found out tonight that monsters in this game actually adjust their attack patterns for different situations.
I was farming in Sunset Flag Forest today.
For those familiar with the zone, it has many transitions points and it looks like your pet can get stuck there.
I didn’t realize it at first and was fighting little lizard guys who CONSTANTLY would cast sleep on you when you attacked. Extremely annoying as melee.
After a little while I realized my pet was missing so I summoned him.
Instantly, instead of casting sleep they would cast a Magnetic Field spell that did nothing (just sucked us in together). It made my kill speed million times faster.
This made me wonder about some other monsters I was grinding and maybe it would be better to put the pet away? Ones with nasty AoE spells.
