Larian Studios Forums Divinity - Original Sin Divinity - Original Sin - General So how does Constitution/Vitality work?

The number of additional HP points per additional CON is a bit weird.
After a respec I got
+128
+136 (08 more than last time)
+146 (10 more than last time)
+155 (09 more than last time)
+166 (11 more than last time)
+178 (12 more than last time)
+190 (12 more than last time)
+217 (15 more than last time)

edit: for other effects the game seems to be rounding down.
