One of the things I've found fun about Eclipse is that every time WOTC published some cheap low-level spell that made some of the other classes stuff irrelevant... those other classes could just take advantage of it.
I believe you have some Innate Enchantment already. I am not sure how much. But...
- Master's Touch (Spell Level One x Caster Level One x Unlimited-Use Use-Activated x 2000 GP x.5 (Armor Only) = 1000 GP. Or 1 CP in Innate Enchantment. This will not extend to learning special bonuses like "Smooth" - but it's a fine shortcut and I think that Xenophon could do with a little cheese.
- Wealth Note: Armor and Shields are treated as one category lighter for movement and special ability purposes, have their armor check penalties reduced by two (zero minimum), and gain +2 bonuses.
6 CP for Lightning Strike Technique (Opportunist/get a chance to make an Attack of Opportunity on any opponent within reach who attacks you and misses). Works. Do you have Combat Reflexes?
When it comes to the rest... basically you've got two levels of Stances here - 2 CP and 4 CP with a total cost of 16 CP. Thus you can use 4 CP worth at a time - one of the major stances (Mouse Flicks Ear and Perfidious Rat Strikes) or two of the minor ones. To make this easier to track, it would be best to break up the two major stances into four minor ones.
Now, you've listed 18 CP for various Stances and this is only 16 CP so far. I'm going to presume that John helps you out by customizing your armor a bit (one of his new powers) - granting you +1 to BAB, Saves, and AC plus a bonus Feat/6 CP. Spending that (and the leftover 2 CP) on more stances will get you to being able to use three of them at a time. Sadly, the GM doesn't like Lions Charge in Stances or Auras or anything else continuous, so how about the other four proposed?
- Blades Of Blood: Presence/all enemies within 10′ are attacked by Persistent Blades (and so are automatically flanked),
- Bloodstrike: +2d6 Sneak Attack.
- Bloodsong: Awareness. The user cannot be caught flat-footed
- Bloodsong Symphony: The user cannot be flanked (requires that Bloodsong Awareness be in use).
- Beasts of Blood: Summons a Dire Wolf to fight for you (As per Summon Nature's Ally in general, Caster Level = Your Level). If you happen to be fighting an undead creature the wolf will look either starving or skeletal, and if you happen to be fighting a construct it will seem to be made of metal, stone, or whatever, but the difference is only cosmetic. This is a great way to keep crowds back and to flank opponents though.
- Drink The Heartblood: Vampiric Touch upon the creature struck.
- Baleful Bloods Call: Attempt to inflict Bestow Curse on the creature struck.
- Blood Poisoning: Attempt to inflict a Poison spell on the creature struck.
- Blood Infusion Stance: Presence/Two L1 effects that apply to the user only. Your Armor is affected by Chitin Mail (Lighter, fewer penalties, no momvement penalty) and your Weapons do damage as if they were one size category larger.
- Invigoration Of The Blood: Presence / Two L1 effects that apply to the user only. Floating Disk (the user may run a few feet above the ground - or above water - and Resurgence (the user gets a second chance on a saving throw once per round) (2 CP).
- Vigorous Flawing Blood: Opprotunist / Each time you make an attack you can take a 5' Stop
- Rage Of Blood (Awesome Wrath): +4 Morale Bonus to Str and Con, +2 Morale Bonus to Will Saves.
That's 25 CP so far.
Shield Wall: That was more a question from John than something to buy - but does Xenophon even use a physical shield, or is he using the Force Shield innate enchantment?
