I'm tweaking my 1/2 hp +1/2 level damage template to run some faster games but I don't want to rocket through things so I'm trying to figure out how many hits it should take to drop a monster.
Not a bad question, but poorly worded. Minions for example are dropped in 1 hit, but if they have some high Def scores, they can stick around a while. Soldiers should be roughly as durable as Brutes, both should be better then Lukrers and Skirmishers. Also, eating some shots from a Rogues sneak attack is different then getting nailed by a Wizards magic missile. or AoE attacks. I would use the Defender and Leader classes as a base line.
A better question:
How many attack rolls from a Defender / Leader should it take to drop a level appropriate monster of a given role?
For a game that you want to have go fast, I suggest the following:
Soldier / Brute: 5 attack rolls or 3 hits
Lurker / Skirmisher / Controller: 3 Attack rolls / 2 hits
Elite Brute/Soldier: 10 attack rolls / 5 hits
Elite Lurkers / Skirmisher / Controller: 8 attack rolls / 4 hits
Solo Soldier / Brute: 20 Attack Rolls / 11 hits
Solo Lurker / Skirmisher / Controller: 16 Attack Rolls / 9 hits
Assuming a party of 4 PC's, that gives you solos that last about 4 or 5 rounds, Elites that can stand up for about 3 rounds of focused punishment. Your Solders and Brutes can square off against 1 PC each and stick around for a few rounds, but get dropped if they are dog piled. Your skirmishers can take a few shots, but need to avoid a toe to toe fight.
In general, if you want to avoid a grindy fight, you just need to make sure the following happen:
- Use monsters with AC / Def scores low enough to let most encounter and daily powers hit.
- Use enough monsters that each player gets a chance to use the at wills a few times, and two Encounter / Daily powers.
- Make sure the monsters get a chance to do their special crap.
I have not really encountered any combats that felt like what I would call a grind myself, though I have been staying very close to the reccomended XP value of a given fight, and I have only played up to level 5 in 4th edition at the moment (I have a somewhat unreliable gaming group that gets hit with long periods of non gaming).
