Your size doubles in all dimensions and your weight is multiplied by 8. This growth increases its size by one category - from Medium to Large, for example. If there isn't enough room for you to double in size, you attain the maximum possible size in the space available.

Until the spell ends, Strength skill checks (Athletics) and Strength saving throws that you make are equal to your Strength score (max 20). Your weapons and armour also grow to match your new size. While these weapons are enlarged, the weapon deals an additional damage die on the weapon but not any magical damage dealt by the weapon.

In addition, you are infused with supernatural hardiness. For the duration, bludgeoning, piercing, and slashing damage that you take from non-magical weapons is reduced by 3 and your AC increases by 2.

Any enlarged item that leaves your possession (including a projectile or thrown weapon) instantly returns to its normal size. This means that thrown weapons deal their normal damage (projectiles deal damage based on the size of the weapon that fired them).

This spell does not stack with other magical effects that increase size.
