You cast the inscribed Summoning Spell, conjuring a creature into a square within range. You must use the Command Summon ability to command the summoned creature(s) as if you had cast it normally.
The caster’s Tier of the Spell is equal to the Scroll’s Tier.
If the Scroll is Tier 1 or higher, you can apply 2 charges worth of Mana Flux in Metamagics to the Spell or Technique per Tier of the Scroll, chosen from the Metamagics inscribed on the Scroll.
Once you learn this Formula, you can inscribe any Summoning Spell with an elemental tag matching one of your Affinities into a Scroll.
