Tips for the Underworld Crypt

Yesterday, my friend (39) and I (34) tried to take on the Underworld Crypt, but failed at any attempt at holding off the monsters. Any tips for this dungeon?

 

First of all, make sure your gear isnt for an outdated level. Some stuff like rings, bracelets, and necklaces are fine, but if you're using a weapon or armor for level 1-20 that could be an issue.

For the first part of it where there's a swarm of zombies, you're able to move spell through pretty reliably, as the mobs have crawl AI (they stop every few seconds when approaching)

For the survive sections between parkour, stay far away from the enemy

For the boat section, try focusing the ranged mobs. The melee mobs have a bit of trouble boarding the boat and while they're trying to get on it leaves them vulnerable for you to kill them.

For the boss, you cannot harm Charon directly. An easy and reliable way to beat the boss is to just summon General Gracken as often as possble
