Overview
Glass bottles provide a portable water source, allow bottling of potions and form the core of Magic Essence, which is used to power much of the advanced magic tools, items and armour found in the game, can be refilled and reused over and over for drinking water (provides 200 Thrist per use twice before empty), but consumed when used as part of magic essence.
