In the first part of Triple Quest 3 - The Portal Perilous, the game's pathing can kill you by automatically moving you to a tile with a blood pool when clicking on a monster whose attack you would just barely survive (So that you move onto the blood, lose health, and then get killed by the Monster's attack because your health is lower than it was when looking at the prediction).
1. Start Triple Quest 3 "The Portal Perilous
2. Find a monster whose attack you will just barely survive and which is also adjacent to a blood pool
3. While standing away from the monster, hover the cursor over it and notice that the auto-move pathing will move your character onto the tile with a blood pool to attack the monster (If not, move to another tile or find another monster)
4. Left Click on the monster to attack it
Does that make any sense? Let me know if you need more info. I guess it's not necessarily a bug, since the game tells me where my character will move when I hover the mouse over the monster, but it's pretty cheap nonetheless
