this goes double for the ranger as its effectiveness is most compromised by close combat.
Actually the Ranger has easiest time in GK's lair because he moves and shoots so fast
that the GK and other enemies can't out-spam him with summoning. You just have to
bring some light-radius gear or use potions of clairvoyance to extend your vision range.
Besides, he's got a guaranteed ally, and its the strongest one in-game when it comes
to Attack/Speed combo, so it's like 2 powerfull fast-hitting characters in one.
As for the original topic:
- Locked gates can only be unlocked with a key or lockpicks.
- Enemies can also be lured into trashing closed doors!
