Message: <blockquote data-quote="Quickleaf" data-source="post: 6953825" data-attributes="member: 20323">[MENTION=6865886]chuckyp[/MENTION] The DMG monster toolkit section doesn't address how giving a monster the power of paralyzation affects its CR.Instead, you need to reverse engineer a simple lower CR monster with paralysis: the Carrion Crawler.DMG Analysis of Carrion Crawler (CR 2)Defense CR = 1/2based on HP 51 & AC 13, conferring with DMG pg. 274Offense CR = 3 (we should expect this to be 3 or 4, based on the Carrion Crawler's CR 2)Bite +4 attack, 7 damageTentacles +8 attack, 4 damage, DC 13 save or poisoned/paralyzed, but target can re-test save at end of each of target's turn So it deals a total of 11 damage. But what about its goofy attack bonus difference?For the purposes of determining its average attack bonus, I'm treating the Bite as worth 64% of its damage and the Tentacles as worth 36% o its damage, therefore its "average" attack can be calculated as...(0.64)4 + (0.36)8 = 3.84 + 2.88 = 6.72 rounded up to 7So its "average" attack bonus is about +7.Based on the chart on DMG pg. 274, this puts its Offense CR at 3 (or maybe more accurately about 2.5).Total CR(0.5 + 3) / 2 = 1.75So it looks like from a straight numbers game that all the Carrion Crawler's form of paralyzation (similar to your Surgeon's) really adds up to in terms of CR is swaying which way the Offense CR rounds (i.e. round up).Next StepYour next step would be to calculate your Surgeon's Offense CR based on a simulate 3 rounds of combat, probably doing something like...Round 1. Syringe/Scalpel/BonesawRound 2. Syringe/Scalpel/BonesawRound 3. Syringe/Scalpel/BonesawDMG Analysis of your SurgeonDefense CR = 1/2Technically this is CR 1/4 according to the DMG, but I could see this being CR 1/2 because his HP are at the upper edge of the CR 1/4 threshold (36-45), and his AC is 14 (vs 13), and has two proficient saves (which the DMG doesn't normally tabulate, but you can argue are worth +1 AC especially since DEX and WIS are the most common saves in the game). Personally, for that reason, I consider its Defense CR to be 1/2Offense CR = 4Total damage 10 (syringe) + 6 (scalpel) + 7 (bonesaw) = 23This puts him at Offense CR 3 so far.His attack bonus of +7, however, bumps him up one step on the DMG chart to Offense CR 4.Total CR = 3(0.5 + 4) / 2 = 2.25Normally, I would round down to CR 2. However, because of the Surgeon's paralyzation ability (and how that synchronizes with other Surgeons to potentially skyrocket the save DC vs. its paralyzation well above the Carrion Crawler), I am inclined to round up to CR 3.Encounter BuildingAnd finally, about how many Surgeons would be a good fight for your party of four 6th-level PCs?Without knowing your party, I can only go off the DMG guidelines, which suggest that 3 Surgeons would make for a Hard fight, while 4 Surgeons would make for a Deadly fight.</blockquote>
