My query stems from this one: Does the Star card from the Deck of Many Issues enhance your skill rating above 20?
How precisely does rising a capability rating above 20, by any means, work in any respect?
Means Rating Will increase: A few of these options help you enhance your skill scores, both rising two scores by 1 every or rising one rating by 2. You possibly can’t enhance a capability rating above 20. -PHB pg. 15
Handbook of Gainful Train: …your Power rating will increase by 2, as does your most for that rating.
Say you’ve got a Power rating of 18, and use a Handbook of Gainful Train to extend it to 20, can you continue to not use an ASI to extend it to 22, regardless of the “most” now being 22? In actual fact, is 20 even the utmost to your skill rating when utilizing gadgets; the quote appears to solely apply to Class Options.
