Chance of Lower Slot
From IUO Tome of Knowledge
Some tameable creatures have a chance to spawn at a lower slot than normal. For example, a White Wyrm is normally 3 slots. But there's a small chance at spawn that it will be 2 slots. This change is visible in animal lore prior to taming the creature.
The following creatures can spawn a slot lower than normal:
- Najasaurus - 1 slot
- Runebeetle - 2 slot
- Greater Dragon - 3 slot
- Frost Dragon - 4 slot
- White Wyrm - 2 slot
- White Wyrm Mount - 2 slot
- Dragon Turtle Hatchling - 3 slot
- Frost Mite - 1 slot
- Dire Wolf - 1 slot
- Skree - 2 slot
- High Plains Boura - 1 slot
- Lesser Hiryu - 1 slot
- Dragon Wolf - 2 slot
- Blood Fox - 1 slot
- Shadow Wyrm - 3 slot
