You could just cast the peasant immortality and then use the peasant to set off traps
Is this intentional?
Welcome to the forum @all_names_were_taken ! 
This is a friendly place where you can ask help on levels, report bugs, or just chat with other coders! Have a great time 
Can you post the link?
Have you unlocked the glaciers?
Also, I don’t want to use pender because she has too little hp.
Yes, i finished all the levels
Well, you doesn’t get bonus
You do, just cast immortal to the peasant and the peasant will survive 
Well, you did a great job
The same thing applies to the almost perfect minefield, apply the immortal to the peasant and then use summon undead to trigger the mine and to keep a distance from the mines to minimize the damage done to you.
Use Ritic if you can
I don’t have ritic bc he is too expensive (29000 gem).
Then how did you pass the level of ritic
I don’t have Ritic too, but I use other heros to pass it
I didn’t, you can progress on without playing that level, it’s kind of an optional level 
.
Well, I can tell you!
I jumped over the fire traps for the first chest and then triggered them with a soldier after I had some money, but yeah, you could do this too :]
