I'm trying to program my Steel Defender so that I don't have to touch him again after I've created him. I tried making an NPC token, but my DM has the Eberron tools and not me. I tried to program it from scratch but found I couldn't put the formula for calculating an HP and just have it show the number. I couldn't put in the Proficiency bonus in the appropriate places. So I opened up a full character sheet and programmed that. That got me farther except the only thing I can't see to do is use my characters Spell Attack for the Steel Defenders Rend. I ended up putting it at 0 and have a global attack bonus that is my character Spell Attack, but this separates the numbers when rolling. Do I have to let my DM set this up for me, or is there a way I can use formulas in HP and Attack?
