Spellslinger

You've learned to maximize the offensive potential of your spellcasting foci, using both of your hands to focus your spells. You gain the following benefits:

• On your turn, when you are wielding two wands and score a critical hit with a spell attack or reduce a creature to 0 hit points with one, you can make one additional spell attack as a bonus action as part of the same casting.
• Once per turn before you make a spell attack while holding a staff or rod with two hands, you can choose to take a -5 penalty to the attack roll. If the attack hits, you add +10 to the attack's damage (if the spell deals damage). If the spell deals more than one type of damage, you choose which type gets the bonus.

• Ordinarily when you cast a spell using a bonus action, you can't another spell during the same turn, except for a cantrip with a casting time of 1 action. You may ignore this rule, casting a bonus action spell and a non-cantrip action spell in the same turn. Once you cast those, you must finish a long rest before you can cast spells in this manner again.
