4e doesn't have hit die... so there's only level.
4e doesn't have hit die. What it has is level and classification. The Solo/Elite/Standard/Minion classification matters. If you do not take this second part into account, no wonder you have problems understanding anything about monsters in 4e.
According to you, a level 3 young white dragon is of lower level than a level 4 orc drudge. Do you really think that this is a fair and accurate reflection of the game? And are you arguing this seriously or rhetorically?
Alternatively you can go by XP value for the encounter as broken down by PCs as laid out in the DMG.
I included HD in reference to earlier editions. And no, it's not moving the goalposts, it's something 4e fans conveniently ignore when talking about the ramped up power feel of 4e characters... yet it plays a significant part in it.
No. It's something you're actively misrepresenting. Possibly you do believe what you are saying and that an orc drudge should be classed as a higher ranking threat to a party than a dragon. Is this the case?
Uhmm, the Young White is a level 3 Solo Brute...
Fledgeling White. Monster Vault. Mea culpa.
The Id FIend is a level one solo and his strongest attack does 2d6+5... so between 7 and 17 points of damage... I'm not seeing a one shot here. So yeah, both examples fall short.
I should have looked that one up as well. Either way, 1 on 1 the monsters will utterly destroy the PCs.
I said by resting... where does "resting" inherently include magic? Unless youre definition of resting is totally different from the definition in the books. they are different dynamics and generate different feels in the game.
Yes. They do. The 3.X healing and crafting rules turn PCs into magic-fuelled supermen who can keep going until someone gets a lucky hit in (this part of the RAW being broken is big enough to warp the whole game). The 4e healing rules actually do eventually force the PCs to stop - and makes them vulnerable to attrition. Neither is like the slow recovery of the AD&D characters.
Edit: The Orc Drudge is most emphatically not a level 4 Standard Monster. He's a level 4 Minion. And should no more be treated as an ordinary level 4 monster should than a Young Black Dragon who's a Solo. The Solo/Elite/Standard/Minion part of the monster matters. And if you wish to ignore it, that's your affair.
Edit 2: And of course the drudge is a commoner. What else would a drudge be in 3.X terms? A warrior? Drudge is right there in the name.
