but the height advantage is what made it so much easier. They've got to get rid of that now. Seriously. It either makes a battle too easy or too hard. If the enemies have height, you get your butt handed to you. If you do, you hand the enemy's butt to them.
Yes, that is still, by far, the biggest variable in any fight.
And I still think Ethereal Jaunt shouldn't allow the Phase Spiders to teleport across the board to kill enemies. That right there is not Phase Spider type activities. They should use Ethereal Jaunt and disappear as a Bonus Action. Then reappear a round or two later on top of PCs, attacking them. Then on the next round, attacking and disappearing again. They are hit and fade enemies, not teleport across the board and spit poison from 100 feet away enemies.
Yes, Phase Spiders teleporting away and spitting at you didn’t feel right. I am not sure Larian will be willing to let you sit for two turns and wait for spiders to reappear.
