Greetings
was curiosu about these so did some testing.
1) act like a normal bandage and give extra healing +4 to +8. so skill 100 normaly 25pts of healing. using these gians you 29 to 33 pts of healing done.
2) testing was done on Human toon with no regen buff on. Toon was beloow 50% health during tests.
3) at a cost of 2gp and change each vs 6sp for basic bandage it is cheaper to go with basic bandage.
