Prerequisite: 5th level
When you cast a warmage cantrip that requires a single spell attack roll, you can select multiple creatures and make a spell attack roll against each. You can target a number of creatures equal to the number of damage dice the cantrip deals, and split your damage dice up amongst your targets, to a minimum of 1 die of damage per target. Each attack must target a different creature.
For example, Fire Bolt deals 3d10 damage. You can choose to target three creatures and deal 1d10 damage to each creature, or you can target two creatures, dealing 1d10 damage to one creature and 2d10 damage to the other creature, or you can target one creature for 3d10 damage.
Whenever you cast a warmage cantrip which deals thunder damage, you can choose for the spell's casting to be magically silent for all creatures other than the target. Furthermore, you can become magically silent until the start of your next turn.

When you finish a long rest, you can place a unique sigil on a simple weapon, which becomes your signature focus until you use this ability again. This weapon becomes magical, and can be used as an arcane focus. Your signature focus is bonded to you, and gains a number of special abilities:
• As a bonus action, you can call your signature focus to your hand, as long as you are on the same plane as it.
• You can add your Intelligence modifier, instead of your Strength or Dexterity modifier, to attack rolls using your signature focus.
• Your signature focus gains a number of charges equal to your Intelligence modifier. When you damage a creature with it or a cantrip cast through it, you can expend 1 charge to deal an additional 1d8 force damage to that creature. Your focus regains all spent charges after you finish a long rest.
When a creature rolls a 1 on a saving throw against one of your warmage cantrips, it automatically fails the save and takes twice the number of damage dice dealt by the spell, as if you scored a critical hit. The additional damage only applies to the creature that rolled a 1.
