yepp. Well, those pots wont be as "advantaging" as yuu may think. The amount healed in total is just 840 hp more. Pots heal for 3 salves each 0,5seconds, at the amount specified in the description.
I made it based on the other potion increases each degree. From Large to XLarge it had a nincrease of 280 hp for the new potion, this one is 280 too.
XL Pots heal 2460 hp (820 x 3) in 1,5 seconds
SXL Pots heal 3300 hp (1100 x 3) in 1,5 seconds
Thats all about it. Not really an advantage, but helping out alot in the end.
Cheers!
