Actually this isn't true. Monsters spawn slowly as you continue to go through a floor; this is why sometimes they'll approach from odd angles in areas you thought you already cleared. This includes elite monsters (which can be a problem if they are spellcasters). There isn't really any point in grinding though; not necessary in this game (or I wouldn't be playing it, I *hate* grinding).
Lets put it this way:
I've had better experiences, better luck, and more success playing Pixel Dungeons than Dungeons of Dreadmore.
I got to level 15 last night on the Huntress (an unlockable class you get access to after beating level 15 for the first time). My
goal last night was to beat level 10. I've been working on this for a few weeks (one run a night, roughly, unless it was short because you can encounter just plain bad luck--"Its safe, I have 2 hp left, and four potions, one of these is probably a healing potion." *Drink* "And now I'm on fire. One action, then I die." *drink* "Ah, that was the paralyzation potion, I'm dead.")
I made one change to my strategy last night. Mostly on accident, as there was no way I was going to know ahead of time how unlucky I'd be with scrolls. If I'd done my usual I probably would have died around floor 4 or 6 (either have just beaten the boss and creamed by the first thing I saw, or not survived to see it).
Items take damage as you use them (that makes sense) but I'd noticed the other day that my starting items only take damage
if they've been upgraded (the "+1" enchantment). So rather than upgrading my boomerang, I upgraded some leather armor I found (which also dropped its strength requirement by 1, which meant it wasn't overburdening me, I had yet to find a strength potion). Helped a ghost, took its weapon (I already had leather armor and anything else would have been too heavy, but my usual tactic is to take the armor, as its always identified and never cursed). Got a 14 strength magic sword (stunning enchantment). Wasn't going to be using that for a while, I was up to a mere 11 strength so far and I had seen only one Upgrade scroll. Eventually found a second and made the choice to ID and upgrade some chain mail (13 str -> 12) instead of repair/upgradinging the leather armor. My DR only went up by 1, but the scalar was better (each +1 on leather is 2 points of DR, but chain mail gains 3).
A short while later, I was defeating the level 10 boss, getting the advanced class manual (which in all future runs I will now start with), and heading down to the teens. Not too long after that I reached level 15 and went to bed (the boss there is really tough).
The only change I made to my runs was
to not upgrade the boomerang. The huntress is very good with projectile weapons, so I'd been upgrading that first, getting the extra damage on 90% of my attacks early. That run, I upgraded armor and only armor, and found a decent weapon to swap out with the dagger I started with (doesn't usually happen, oddly enough, due to the strength requirements and the relatively few strength potions--e.g. I've found 6 in 15 levels (giving me a strength of 16) and the best armor and weapons in the game take 18 strength, which I've found on level 1 before). I think I found a total of 3 scrolls of upgrade, which is
awful. I normally have that many by floor 5, if not, I can pick one up at the shop on floor 6. No, this run gave me lots of scrolls of remove curse (which you need like one or two of, tops, because cursed items are still negatively enchanted--its easier to just not equip unidentified items).
It probably helped that I murdered two shopkeepers (there's only one way to do that, and it's by finding a shine room, killing five monsters while you--or they--are standing on the altar, at which point the room turns off and you get a Scroll of Wipe Out, which kills
everything currently on the floor. If you're standing on the altar when you kill monster #5, the buff you get for standing there will last another 5 turns or so. If you kill another monster in this time, you get another scroll of wipe out; I've never gotten more than two, and I got two last night) and totally stole all their stuff. Which was mostly "I'm not paying for your overpriced rations and I'm starving" but I also got a handful of other useful things. But I don't attribute this to the difference between a successful run and an unsuccessful run, I had a run about two weeks ago where I died
holding two scrolls of wipe out because I never got to use them (i.e. never reached level 6). I attribute killing the shopkeepers as allowing me to survive to level 15, rather than just level 10, as I've never gotten this far and
not killed at least one of them.
To give you an idea of how powerful what you decide to upgrade is, I started favoring the mage heavily because once I got the class mastery book, one of the options is Battlemage, which:
- lets you equip wands as melee and do boatloads of damage (3 + N where N is how many charges it has, minimum 2)
- hitting a monster with a wand and doing at least 3 damage (after armor) recharges it one charge
You also start with a wand of magic missile for being a mage (a great short and long range weapon; wand of lightning is better at both damage and has AOE, but you can hit yourself with it too).
The first ability is basically "you don't need a melee weapon, you can stop using scrolls of upgrade on melee weapons" reducing your scroll requirement
by a third (melee + ranged + armor -> wand + armor). The free recharging is just candy. Use a charge (wand effects always hit), melee the monster, use a charge, melee the monster.
The mage is the only class I've been to level 15 with before (three times, even). I figured the huntress's boomerang would function similarly to the wand of magic missile: giving me good long-range damage that I could also use in melee. In practice I was wrong. It's accuracy is lower than a dagger, so once a monster is in melee range, I'm better off stabbing it than using the boomerang, even if the boomerang is upgraded twice and the dagger isn't. This is particularly noticeable against monsters that start showing up on level 3 and becomes a big issue once you reach level 6.
I've
never had runs like that in Dreadmore, where altering my strategy just the tiniest bit has made such a huge difference. No, in Dreadmore I'm constantly scrabbling for any item better than I started with and never getting it. I've even tried a class that can craft weapons or armor and that only means that I'm scrabbling for the crafting resources too. I still never find better stuff, the crafting helps a little, but I still end up just shy of an upgrade more often than completing it. And then I die.
