I am going to play my first glass cannon (Zen Archer, indeed) and I dont know to apply weapons blanch on my arrows.
These alchemical powders have a gritty consistency. When poured on a weapon and placed over a hot flame for a full round, they melt and form a temporary coating on the weapon. The blanching gives the weapon the ability to bypass one kind of material-based damage reduction, such as adamantine, cold iron, or silver. The blanching remains effective until the weapon makes a successful attack. Each dose of blanching can coat one weapon or up to 10 pieces of ammunition. Only one kind of weapon blanch can be on a weapon at one time, though a weapon made of one special material (such as adamantine) can have a different material blanch (such as silver), and counts as both materials for the first successful hit.
The question are
1. Do i need a forge or some special tipe of great fire? or I can apply the weapon blanch with a bonfire, torch or something similar
2. the statement says "temporary" How much time is it? until arrow is used? I guess the answer is yes and temporary only means that it is nos permanent, But i would like to have confirmation.
Thank in advance
