Your touch causes the target to grow an extra pair of arms. If the target is unwilling, it can make a Constitution saving throw. On a success, the spell has no effect.

For the duration of the spell, the target can use two-weapon fighting with both ranged and melee weapons, which need not be light. If the target makes an attack with a light melee weapon, it can use its bonus action to attack with two different light weapons that it's holding in its other hands.

Until the spell ends, the target also has advantage on Strength checks and Strength saving throws, and gains a climbing speed equal to its walking speed.
