Light spring water fizzes and bubbles within this small glass globe, spilling onto the affixed armor when activated.
Until the end of your turn, the armor lets you move across water and other liquids as if they were solid ground. If you Stride or Step over a weight-sensitive pressure plate, you don't cause the plate to depress, which prevents you from triggering any device or hazard attached to the pressure plate.
When the ampoule's effect ends, you sink, fall, break through flimsy ground, or land on pressure plates as normal for your current location.
Traits
Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
ConsumableAn item with this trait can be used only once. Unless stated otherwise, it's destroyed after activation. Consumable items include alchemical items and magical consumables such as scrolls and talismans. When a character creates consumable items, they can make them in batches of four.
MagicalSomething with the magical trait is imbued with magical energies not tied to a specific tradition of magic. A magical item radiates a magic aura infused with its dominant school of magic. Some items or effects are closely tied to a particular tradition of magic. In these cases, the item has the arcane, divine, occult, or primal trait instead of the magical trait. Any of these traits indicate that the item is magical.
TalismanA talisman is a small object affixed to armor, a shield, or a weapon (called the affixed item). You must be wielding or wearing an item to activate a talisman attached to it. Once activated, a talisman burns out permanently.
TransmutationEffects and magic items with this trait are associated with the transmutation school of magic, typically changing something's form.
