Venerable: Glancing or penetrating hits against the Venerable Dreadnought may be re-rolled at the defending player's discretion
so it means that i get to ask for reroll on penetration dices and not on the results on the damage chart, am i right?
if yes, that doesnt do much on melta shots but help better on plasmas, krak grenades, etc... right?
Thanks you alot!
