Alternate Version of Nifty with her and her robot buddies being prepared for combat.
Niftys goggles of day carry a homebrew artificer infusion. They counter her sunlight sensitivity making her way more effective for a party that doesn't crawl around in dungeons all the time. Her weapon is also the result of an infusion used on a battle axe. With the press of a button the safety shell retracts and reveals a circular saw blade. Fitting for a weapon that uses the intelligence modifier for attacks. On her left arm Nifty carries her Bracelet of Defending that is used for spells like Shield or Absorb Elements. Most of her other spells are delivered by tiny spiderlike robots.
Nifty is well equiped for melee combat. Especially with Drake by her side giving her advantage and the enemy disadvantage on the attack roll. But maybe I could make her deadly in ranged combat too. If the DM allows it I would like to attach a heavy crossbow between Drakes shoulders. Drake cannot use it but Nifty if she rides on his back. Since Drake carries it Nifty could be able to use it without disadvantage and the Repeating Shot infusion would allow her to use the extra attack with it. If this would be possible I would also give her the Sharpshooter feat increasing her possible damage output even further.
