Short Guide About Monster Behavior
1 - Rat
Look at the direction the rat is facing — it shows where the Rat King is. If the rat is standing still, it means the Rat King is in that column.
4 - Four-Hand Monster
It always has a twin on a border cell (left, right, top, or bottom).
6 - Guardian
It is always next to a chest (orthogonally or diagonally). Look at its sprite — it will tell you if the chest has already been looted.
8 - Purple Slime
They always form a defensive formation around a mage. The mage has 1 HP — kill him to get a scroll that reveals all slimes.
9 - Lovers
Each holds an HP scroll. Their sprites face each other.
10 - Mine King
Always located in one of the four corners. Kill him to destroy all mines, leaving loot worth 3 XP (you still need to find it).
5 - Beholder
He hides number values nearby. He has a range of 2. You can deduce his location by the shape of the "?" markers — but be careful, there may be more than one.
0 - Gnome
He runs away when clicked. After a while, he will give you 9 XP.
