It's max of ALL dice plus one die (your choice of which one)
So damage is
Slashing(1d4+5): 4+5 =9
Radiant (2d8): 16
then add any one die of your choice...in this case I assume you'd want 1d8 of radiant. So if you choose this option total damage is 25+1d8.
-or-
You can just double all dice:
Slashing (or piercing or whatever daggers do): 2d4+5
Radiant: 4d8
If you choose this option just roll another 1d4 and your total damage is 7+1d4 slashing and 25 Radiant (so 32+1d4)
It's more swingy...with better potential for very high or very low damage. The Max+one die method is higher on average but more steady. As the DM, I roll more crits than the players so I choose Mzx+one die because swingy PC damage can be bad (imo)
Choose one. All I ask is that folks pick one and stick with it so we aren't deciding after we see some of the dice rolls.
Nice Crit,BTW. Add some good narration if you'd like. You will do about one fourth to one third of her max hp in damage, all told.
Then it is Erevan's turn [MENTION=6776182]JustinCase[/MENTION]
Erevan drops his magical disguise with but a thought. Where before a chained dusky elf was, now stands a noble elf packed with weapons. He doesn't wait a moment, handing the others their respective weapons before grabbing his own bow and arrows.
OOC:
That's my whole turn, right? Or can I still attack?
I really want to avoid worrying about rules regarding equipping, stowing, handing etc. It distracts from the fun, IMO. So we'll make it easy:
If you are fine handing out all the weapons and that's it for your turn, then we'll go with it. If you want to be able to attack, I think it's fair to say you can hand one weapon to one character, equip your own weapon and attack(and drop all the other weapons and such at your feet). Sound good?
Ez has a weapon. Orsik can just cast spells or cantrips. So if you want to get off an attack this round, you can hand Surana a blade and then fire an arrow and let others worry about picking up their own weapons. It shouldn't be a problem as long as they can get within reach of your square. I am assuming you all are in reasonably close proximity (Ez up front, you and Surana just behind and Orsik and Ploop behind them).
Don't forget those rogue bonus actions! In our table game last night the monk managed to turn a half dozen hits into misses with dodge over two rounds of combat. She was tanking as well as the paladin. Dodge or disengage to move out of the fray are great options. You are all pretty much surrounded by enemies.
Oh right, I forgot about Cunning Action! In that case, I get one bonus action I can use to handle an object. So shoot an arrow, then give a weapon to Surana, giving the others the possibility of getting theirs on their own turn. Sounds good to you guys?
