I had Lazeal stand at the bottom of the ladder right behind where the goblin stands to officiate the chicken chase event with the rest of my toons at the top of the ladder raining down death. None of the enemies got past Lazeal and climbed up the ladder. I used the same tactic to fight the group of oath breakers looking for Karlach, Lazeal held the base of the ladder in the main room and the rest of my toons where up top. It may indeed be possible for enemies to reach past and climb anyway,, but I haven't seen it happen yet.
Ah, good to know! I assume it has something to do with ladders not actually being surfaces you can stop in the middle of. If an enemy can begin climbing a ladder, then they have to be able to get off at the top or else that'd break the game/otherwise have wonky results.

Similarly, I imagine you could stand at the top of a ladder and prevent enemies from climbing down. You just can't stand at the top of a ladder and prevent enemies from climbing up, or the the bottom of the ladder to prevent enemies from climbing down...

To move this thread somewhat more on topic, it'd be neat if "ladder climbing speed" was a toggle option.
