Il maglio sterminatore è una tipica scelta trappola, che sembra appetibile sulla carta, ma in realtà è molto subottimale. Purtroppo ci siamo cascati in tanti, metto quindi qui un'analisi che aiuta a capire tutti i suoi punti deboli (da brilliantgameologists)
Spoiler:
Logical Entry: Swashbuckler 5 (uses all your feats though, so Fighter 5/Monk 1 may be preferred)
Cons: Requires Clever Wrestling, which is the worst thing it could do for a grappling class. If you don't know, clever Wrestling requires you to be small or medium size. And what's the best way to get higher Grapple checks, or even be able to grapple larger opponents? Why, GETTING SIZE MODIFIERS. Thus, to take this grappling-based class, you BECOME WORSE AT GRAPPLING.
At Reaping Mauler 1, you gain Improved Grapple... If you haven't taken it by 6th level anyway (You can get it at Monk 2, it's a Fighter bonus feat, etc.) There's no excuse for a Grapple-based character to NOT have Improved Grapple by 6th.
You are supposed to wear light or no armor to use the class features, but you lose your Dex bonus to AC when grappling! Your AC while grappling will be even worse than it already usually would be. Also, Rogues would love you. Allies and Enemies alike.
The class feature Counter Grapple makes you better at escaping a grapple, which does nothing to help you actually be GOOD at grappling. Even Adept Wrestling barely helps, because it's only a +2, which is pathetic against monsters that will often have grapple checks in the 30's, 40's, or 50's. You get no real outstanding class abilities until Sleeper Lock.
Using Sleeper Lock with reliable success requires a high Wisdom score, making the MAD even worse. Even if your Wisdom is through the roof, and so your save DC is, too, it still won't work on amorphous creatures. Devastating Grapple suffers from the same save DC issue, and also requires 3 consecutive rounds of pinning your opponent. Either you need to be very lucky to pull that off, or you need to be so much more powerful than your opponent that the fight will likely not be worth any XP and will likely not be a fun challenge.
You get Mobility without Dodge as a prerequisite. This isn't bad, until you realize that you lose the bonus the minute you attempt to grapple, as you'll lose your Dex to AC.
Basically, grappling is a less powerful contribution to combat than, say, debuff spells. This fact doesn't make grappling worthless, but you will want to boost your grappling abilities pretty high to be a credible threat against anything but your basic medium-sized humanoids. The Reaping Mauler does NOT help you in this regard.
Oh, and your entire grappling focus? Useless versus A) A 40k ring. or a 4th level spell.
Pros: You get 2 Feats (that both ignore prerequisites) and mild bonuses to grapple checks. Full BAB, d10 hp, and good Fort and Reflex saves are also not bad.
You can take the E out of Reaping, and have an immature giggle as they grapple/pin random NPCs. Even more so if you have Sleeper Lock (makes them unconscious) and Devastating Grapple (kills them). -Chaos Josh
