Formation. As long as two or more other creatures with Formation are within 5 feet of the soldier, the soldier has advantage on saving throws made to maintain concentration, and it has access to its Arcane Shielding.

Spellcasting. The soldier is a 3rd-level spellcaster that uses Intelligence as its spellcasting ability (spell save DC 13; +5 to hit with spell attacks). The soldier has the following wizard spells prepared:

Cantrips (at will): fire bolt, lightning lure, shocking grasp

1st Level (4 slots): color spray, mage armor*, magic missile, silent image

2nd Level (2 slots): scorching ray, web

*The soldier casts this spell on itself before combat begins.

Shocking Grasp. Melee Spell Attack: +5 to hit, reach 5 ft., one target. Hit: 4 (1d8) lightning damage, and the target can't take reactions until the start of its next turn. This attack has advantage if the target is wearing metal armor.

Fire Bolt. Ranged Spell Attack: +5 to hit, range 120 ft., one target. Hit: 5 (1d10) fire damage.

Arcane Shielding (Formation Only). In response to the soldier or a creature with Formation within 30 feet of the soldier being hit with an attack, the soldier expends a spell slot from its Spellcasting feature. The creature gains a +2 bonus to its AC, possibly turning a hit into a miss.
