Mice start at Level 1.

The following table shows the total XP required to advance each Level.

Level	Hit Dice	Grit	Experience points
1	1d6	0	0
2	2d6	1	1000
3	3d6	2	3000
4	4d6	2	6000
5+	4d6	3	+5000

When your mouse earns enough XP to advance to each Level, use the following procedure.

• Roll for attribute increase: roll d20 once for each of your mouse’s STR, DEX and WIL. If a result is higher than the attribute’s current value, increase it by one.
• Roll Hit Dice: roll the dice listed for the new Level’s Hit Dice. If the value is higher than your mouse’s current HP, replace your HP with the rolled value. Otherwise, increase your mouse’s HP by 1.
