# Intro :::info If you are looking for how to evaluate a Pokemon instead, check [Evaluating a Pokemon]. If you are looking for some nuances about Helping Bonus and/or how our site handles it, check [helping bonus calculation model](https://pks.raenonx.cc/en/docs/view/calc/helping-bonus). ::: Subskills are a series of passive skills unlocked at Lv. 10, 25, 50, 75, and 100. They are bound to an individual Pokemon, and the player can see them right under the [Carry Limit] in-game for each Pokemon. For the full list of available subskills and their effects, check [Subskill List]. When you have [Caught a Pokemon], the rolling probability for subskills is not equal-weighted. See [Probability Distribution] for the exact rates. # Subskill Upgrade Subskills can be upgraded using [Sub Skill Seed](https://pks.raenonx.cc/en/item/source/33) if the [Subskill List] indicates they're upgradable. Subskill upgrade is only available for the unlocked ones. For example, if the subskill combo is `Helping Speed S @ 10`, `Inventory Up S @ 25` with the Pokemon currently at Lv. 15, then the upgrade only happens on `Helping Speed S`. Using the same example, if the level becomes 25 instead (so 2 upgradables unlocked), then the game randomly chooses one to upgrade. [Subskill List] also lists what subskills can be upgraded, and what they become after upgrading. ## Usage strategy Most players only upgrade subskills if they deem the Pokemon worthy of investment. This requires full understanding of [Evaluating a Pokemon]. Since subskill upgrade is semi-controllable, it's recommended to upgrade before unlocking a new one to make sure the upgrade lands on the subskill they want to upgrade. ## Site Features The following site mechanism allows automatically applying all possible subskill upgrades. They are mostly provided as premium features: - "Fully Upgraded" preview mode, which can be seen in [Rate my mon](https://pks.raenonx.cc/en/rating), and [Pokebox](https://pks.raenonx.cc/en/team/box) - "^ Max" at the top-right of the subskill selector [Subskill List]: TODO [Caught a Pokemon]: TODO [Probability Distribution]: TODO [Evaluating a Pokemon]: TODO [Carry Limit]: TODO
