Jumping Thunder set bonus should be 150%, this way the sum for all 3 parts of Jumping set would amount to 500% [170% clothing 130% weapons 200% mount set], so sleeping at large fort in full Jumping takes exactly 1h of sleep for full regen
after a certain amount, the more you add the less powerful the extra regen is, so at 100% set bonus the sum is 450% and it takes 1h06min for full regen at fort..... please cap that extra 6 min, it is a premium mount and 50% more regen makes for a 6 minutes difference, like a pea under 20 mattresses and 20 blankets
unless you are tank after hp, Jumping clothing + weapons and Santa reindeer amounts to 370% regen and takes 1h16min to regen fully at fort, currently a full Santa takes about 1h46 min, so buying the Jumping horse will cap 10 minutes only. please round it to 16 minutes
the math i'm using is [6 hours / 1 + x% regen], so [6h / 1 + 500% = 6h/6 = 1h], please correct me if i'm wrong about it
