I didn't think it would be too long to save only before the dungeon considering there is only 3 fights there and I was worried if someone managed to enter without the necessary tools to win and is using only one save and saved inside so now they just lost their save and must restart.
You probably didn't notice but when you defeat the group blocking the entrance you get all the xp you lost back with a bonus. And it is actually possible to win agaisnt the ambush if you grind long enough with the right build, comp and a little luck.
I can probably find a way to introduce build slots for players to save different build of summons and skills, that is a good idea.
One thing that is already comming on the next version is using the keyboard to select skills.
I could probably clarify it there when the shaman says she can't help you directly that it makes sence with what you know about dungeon contractors, it will help in making the players to thrust her, although when she stops you from getting hit by a trap is also a good sign that she is trying to help.
