Evolution

When monsters are tamed, and especially when created as familiars, they have the potential to gain levels by killing monsters, just as the avatar does. The avatar can also give them more experience directly, with the Transfer Knowledge spell.

Certain monsters have the potential to "evolve" directly into more powerful forms as they gain levels. Some monsters have only one "advanced form" available, while others, like the familiar Bat, can go through two or more extra forms in sequence.

When a creature evolves, its hit points and maximum mana get rerolled based on their new monster definition. This will erase both the effects of system shock, and any gains from drinking potions or eating corpses.

The list follows:

• (level 1) Mouse --> (level 2) Rat --> (level 3) Giant Rat
• (level 2) Bat --> (level 4) Large Bat --> (level 7) Vampire Bat
• (level 3) Brown Slug --> (level 6) Purple Slug -> (level 12) Death Slug
• (level 3) Cave Spider --> (level 8) Giant Spider
• (level 4) Tridude --> (level 13) Red Tridude --> (level 15) Blue Tridude --> (level 17) Purple Tridude
• (level 6) Kobold --> (level 14) Kobold Fighter --> (level 25) Kobold Thief
• (level 8) Troll --> (level 16) Cave Troll
• (level 9) Kobold Mage -> (level 20) Kobold Assassin
• (level 12) Orc --> (level 18) Hill Orc
• (level 15) Turtloid --> (level 20) Large Turtloid
