It is 10 that actually work.
They can have more than 10 in reality, but it still effects them like they had 10.
The only propose sticking more than 10 would do is for like Healing Breeze (If you stuck 15 pips of degen on them - and they healing breezed to get5 pips of regen, they would still suffer 10 pips of degen - because they literally have 15 pips of degen to start with - but only suffer from 10 of them max)
