Evolutions
All pokemon available in the game will be able to evolve at least once. Evolutions are randomized, but with some logic:
- The evolution will share a type with the previous form, and will be of approximately similar BST to what it is “supposed” to become (usually within +/-10%).
- Everstones are allowed if desired, if acquired by a prize. Roguestone use is a choice.
- Evolutions in RogueMon will SHARE BST distribution AND ability. Any additional BST from the evolution will be randomly distributed ON TOP of the previous mons.

All evolution items in RogueMon were removed and replaced with a “Roguestone”. A Roguestone is an ‘omni’ evolution item. It evolves any pokemon that would otherwise evolve using an item.
Unique Evolution Methods
| Roguestone | Friendship | BST/10 |
|---|---|---|
| Roguestones are offered when completing milestones in your run at a cost (or free) based on your Pokemon’s BST. | The base friendship of your Pokemon is set according to it’s starting BST so that it evolves earlier the lower it is. | If pokemon is <= 450 BST, it will still evolve even if it would not normally. |
| BST <291 Brock for -50 HP cap Mt. Moon for free |
BST <291 - Friendship = 200 | A target will be chosen within a 10% range at +100 the current Pokemon’s BST. |
| BST 291 to <=320 Brock for -100 HP cap Mt. Moon for -50 HP Cap Misty for free |
BST 291 to <=320 - Friendship = 180 | The Pokemon will evolve at the BST of that target, divided by 10. |
| BST 321 to <=370 Misty for -100 HP cap Lt. Surge for -50 HP Cap Rock Tunnel for free |
BST 321 to <=370 - Friendship = 120 | The Pokemon will still share a typing with it’s predecessor. |
| BST 371+ Lt. Surge for -100 HP cap Rock Tunnel for -50 HP Cap Erika for free |
BST 371+ - Friendship = base | Example: If Wobbuffet (405 BST) were to evolve into Delphox (534 BST), this evolution would occur at level 53. |
