Make mounts level faster or slower

Tamed mounts earn experience as they ride, follow, fight and spend time with their owner, level up, unlock their abilities and earn points for their skill tree.

The one number most servers need

# fantasy-server.toml
[progression]
    # 2.0 levels mounts twice as fast; 0 stops levelling.
    xpMultiplier = 2.0

Switches

Also in [progression] of fantasy-server.toml:

Setting	Off means
enabled	No levels at all: every ability is there from taming and nothing grows. Progress is kept for when it’s back on
lockAbilitiesByLevel	Every ability is there from taming, while levels still raise stats
statGrowth	Levels don’t raise stats
skillTrees	No skill points, and learned skills have no effect

skillResetMode decides how owners change learned skills. "RESPEC" (the default) lets them unlearn skills on the mount’s profile and pick others, then wait respecCooldownSeconds (10 minutes) before unlearning again. "TONIC" allows it only with a Renewal Tonic, which resets every skill at once.

Fine-tuning

In fantasy-balance.toml:

• Each activity: under [progression.xp], riding, following, nearOwner, abilities, combat, feeding, breeding and tending each multiply their own XP. 0 turns that activity’s XP off.
• The curve: XP from one level to the next is xpBase + xpGrowth x level^xpExponent. As shipped, that is 140 XP for level 2, about 4,600 in all for level 10 and 59,000 for level 30. A new curve re-levels mounts from the XP they already have.
• The cap: maxLevel (0 keeps each mount’s own, 30 for every shipped mount).
• Skill points: skillPointsPerLevel (-1 keeps each mount’s own, 1 for every shipped mount).

Skills a lower cap or fewer points no longer cover rest, kept, until they are covered again.
