Innate Spellcasting. The gnomeant's spellcasting ability is Intelligence (+3 to hit with spell attacks). The gnomeant can innately cast the following spells, requiring no material components:

Aggressive. As a bonus action, the creature can move up to its speed toward a hostile creature it can see.
Magic resistance. The gnomeant has advantage on saving throws against spells and other magical effects.
Magical Body. The gnomeants body disappears if it enters an anti-magic field or other similar effect. When this happens, only the head remains, its movements speed is reduced to 0, and it is prone. If a spell like dispel magic is used on the gnomeant, it's body disappears for a brief moment, causing it to fall prone.
Sturdy. The gnomeant cannot be pushed back, and has advantage on any saving throws that would cause it to become prone.
