New commenter (and probably not a frequent one.) I like this Racial Character Class (to use the Rifts terminology), and - along with Northlands - it's a really nice addition to my group's post-Ragnarok game. R.A. Boettcher and erian_7 already addressed several of my questions, but I do still have a few things that I'd appreciate clarification on.
1. Terrain Mastery (fire): Gives a bonus to "Jumping" skill checks. Should this be expanded to Acrobatics, or amended to specify that it adds to Acrobatics skill checks for Jumping?
2. Dark Vision: Any particular reason only Aspect (ogre) and Aspect (troll) Jotuns can get this one? They aren't the only types of giants who have it (stone immediately comes to mind).
3. Elemental Sheath: Usage is a bit oddly phrased, but I'm assuming it works like your explanation for Elemental Aura, so the 6th level Jotun Paragon with 16 Constitution could use it 7 times per day for 3 rounds each. My question is, is the sheath attached to the character or to the weapon? If our fire aspect Jotun put an elemental sheath on his sword and handed it to a friend, would it still be on fire? If he puts the sheath on a rock and throws it, does the rock do extra fire damage to the target? How about arrows?
4. Energy Resistance/Immunity: At 10th level, this gives a vulnerability to the opposing element. The Aspect of... feats also give a vulnerability to the opposing element. Do these vulnerabilities stack?
When the Jotun gains their elemental subtype at 10th level, should they get any of the abilities that go with them? Most relevent, "Air creatures always have fly speeds" and 'Creatures with the water subtype always have swim speeds and can move in water without making Swim checks. A water creature can breathe underwater and can usually breathe air as well." Given that, for example, there is a Water Breathing elemental power that has higher prerequisites than Energy Resistance, I assume this is not the case.
That said, any suggestions for how an Aspect of Water Jotun *could* get a swim speed? Even Terrain Mastery (Aquatic) only gives a bonus to Swim skill checks.
5. Jotun's Bag: Is this a reference to something that got cut from the book? The only reference I could find was in the Elemental Power.
6. Fling and Jotun's Bag: Both of these reference an opponent "two size categories smaller than you". All the other manhandling abilities talk about opponents two or more size categories smaller, or within one size category. Does these two really only work on opponents exactly two size categories smaller?
7. Regeneration: This is written with the 3.5 version of Regeneration, not the Pathfinder version. Is that intentional?
8. Stone-Touch: Usable for a number of rounds equal to Constitution modifier (minimum 1; henceforth 'x'). No mention of number of times per day. Is this one of those "can be used for x rounds per day, in any combination" abilities, or as a spell-like ability does it just need to be reactivated every x rounds (as a standard action that provokes attacks of opportunity)?
9. Size Increase: The bit about equipment resizing is also oddly phrased. As written, only equipment the Jotun "possesses" (as opposed to actually having equipped) at the time they level up will change with them. First, does possess mean own or have equipped, and second when is the Jotun considered to be leveling? In every group I've gamed with, that's something that happens during downtime over the course of days to months.
10. Rock Throwing: It says damage is "generally" double slam damage. Is this an instance where size really does matter? Is a 20th level Jotun paragon throwing a Tiny rock going to do 8d6 damage (double their slam damage) or 2d6 damage (double the slam damage of the smallest size that can throw it)?
11. Oversized Weapon: Apparently lifted straight from Cloud giants, who are always Huge. Should that actually be "can wield weapons of one size category greater than normal that you are proficient with without penalty", or can a 13th level Jotun paragon wield a Gargantuan weapon with no penalty even when he's Medium-size?
12. Militant: By 19th level, I think most Jotuns will have figured out what weapons they're going to be using all of the time. In other words, it appears to be of very limited utility based on when it would appear in a campaign. It feels to me like "Well, we needed to give them something that level, and Militant is an ability that two kinds of giants get."
13. Awaken Elemental Power: It says each natural attack needs to be enchanted. Would a single enchantment work for their Slam power, or would they need to do it twice since there are "two" slam attacks?
14. Pinning Throw: Is there a magical component to this feat? As written, a high-Strength Jotun could pin even strong opponent with a 5 pound rock (that really, anybody with a Strength of greater than zero should be able to move it off of them.)
15. I'm just curious about whether there should be an Extra Elemental Power feat. Commentary: While it's true that this is generally more powerful than a single feat, comparable to Extra Mercy/Revelation/Etc. from other classes. Just like the Favored Class bonus to learn a new spell is more useful for spontaneous spellcasters than prepared spellcasters.
