This purple potion has a bitter taste and seems to blur with motion. When you drink a time shield potion, you are frozen in time for 2d4 rounds. You can't act or be targeted, you become immune to all effects, and you vanish from your space; as far as the universe is concerned, you simply don't exist as long as the potion lasts. The durations of any effects targeting you when you drink the potion are suspended until it wears off.
Once the potion's duration expires, you return to the normal flow of time and your former space; if that space is now occupied, you get shunted to the nearest unoccupied space. Effects with durations immediately resume affecting you, elapsing as though no time has passed. If you are within the area of an effect created while you were outside of time, you immediately take those effects upon returning. The GM might determine that other changes that occurred while you were outside of time (such as the ground beneath you crumbling) also affect you upon your return.
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.
PotionA potion is a magical liquid activated when you drink it.
TransmutationEffects and magic items with this trait are associated with the transmutation school of magic, typically changing something's form.
