Won't work that way. The fighter's effective initiative becomes one better than the monks due to his readied action; this means that when the next round starts, the fighter gets to go first. You're trading 6 attacks for two.
And you are assuming that the spellcaster with Haste memorized (Grease is also helpful in this situation, and you'll just pray that he doesn't have Dispel Magic memorized or on a scroll) didn't make his saving throw . . . if he did, and can buff up the fighter (who probably has around 50hp), and you're in trouble.
Actually -- just had a thought. Correct me if I'm wrong . . . but people stuck in a web, *even* if they fail their save, can still cast spells, right? They just have to make a not-too-difficult concentration check (assuming they maxed ranks it in).
Meaning that even if they failed their saving throw against the Web, you have to worry about Dispel Magic, or Haste on the fighter, or Grease on the fighter to help him move through the web, or whatever. Don't think it's going to work. If the monk had a better AC (21, *with* Haste, isn't very good for a 7th level character who gets into combat) he'd be better off.
Yes, the concentration check is 15.
I do not want this to boil down to a debate about the value of the web spell. Merely wanted to make a monk that would be a challenge to this party of level 5.2 adventurers in a catacomb.
I will get away from the web spell in just a sec. In general, many would make the save, some would not, but everyone would be hampered by the webs until it was gone. The monk could simply attack the last guy in line (or the first). Everyone that wanted to help would have to wade through the web and that would be slow going.
Instead of taking the first or last guy in line, take out the mage if he can reach him. The DM would have to decide on how effective unstuck people could attack in the web, being "next" to a person might not make attacking any easier.
I forgot the party makeup, assume a ftr, a barbarian, a wizard, a cleric, and a ... rogue. In a line there has to be an easy(er) target to attack.
perhaps the best target at the time would be the cleric, or the rogue.
A bull rush would work well here, because everyone you moved any at all would be entangled.
grappling entagled targers would be fun

They would have the penalties and you would not.
I did not want to go through every permutation of what you can do with the cloak of arachnid. What I did want to do is make a level 7 monk that would be a challenge to the party. Everyone (well, at least me) expects the party to win, just like they would win if attacked by a level 7 fighter, or barbarian, or bard, or rogue, or cleric.
The killer item is not the cloak but the belt, the haste allows a lot of things to happen. Also, the kama was chosen to overcome DR, lose the kama and the belt, replace them with a circlet of blasting (minor), a potion of haste, and a bead of force. The bead does 5d6 and failed saves lock you in wall of force prisons. The circlet does 3d8 against one target once per day. those two items alone could take out the wizard before melee even starts.
A CR 7 should take 25% of a party of 4 level 7 characters resources. I think a party of 5 with an average level of 5.2 plus the centaur character are pretty close to that level of power. So, seeing if my monk takes 20-25% of their resources would be the test.
