First, the construct type grants Low-Light vision and Darkvision 60 feet. I think it would be appropriate to add those to Ice Body as gained traits.
Frozen Faculty Overhaul ThoughtsRename Physical to Body and Mental to Mind. Add Spirit.
Replace 5th level Ice Power with Frozen Faculty Furtherance(will contain Mental and Physical faculty improvement as well as the upgrade for Spirit).
Replace 10th level Ice Power with Frozen Faculty Finality (will contain Mental and Physical faculty reformation as well as the final upgrade for Spirit).
This leaves us with 13 choices out of 18 options which seems good but if this needs more options let me know.
Frozen Faculty SpiritInstead of focusing on mental or physical prowess, the Ice Beast instead focuses on improving their connection with the ice that they are made from. This class feature modifies the Ice Body class feature, granting the Ice Beast the Living Constuct subtype in addition to the Construct type, gaining the following traits instead:
- Unlike other constructs, a living construct has a Constitution score. A living construct does not gain bonus hit points by size but gains (or loses) bonus hit points through a Constitution bonus (or penalty) as with other living creatures.
- Unlike other constructs, a living construct does not have low-light vision or darkvision.
- Unlike other constructs, a living construct is not immune to mind-influencing effects.
- Immunity to poison, sleep effects, paralysis, disease, nausea, fatigue, exhaustion, and energy drain.
- A living construct cannot heal damage naturally.
- Unlike other constructs, living constructs are subject to critical hits, effects requiring a Fort save, death from massive damage, nonlethal damage, stunning, ability damage, ability drain, and death effects or necromancy effects.
- Living constructs can be affected by spells that target living creatures as well as by those that target constructs. Damage dealt to a living construct can be healed by a cure light wounds spell or a repair light damage spell, for example, and a living construct is vulnerable to a harm spell. However, spells from the healing subschool provide only half effect to a living construct.
- A living construct responds slightly differently from other living creatures when reduced to 0 hit points. A living construct with 0 hit points is disabled, just like a living creature. He can only take a single move action or standard action in each round, but strenuous activity does not risk further injury. When his hit points are less than 0 and greater than -10, a living construct is inert. He is unconscious and helpless, and he cannot perform any actions. However, an inert living construct does not lose additional hit points unless more damage is dealt to him, as with a living creature that is stable.
- Can be raised or resurrected.
Frozen Faculty Furtherance (Spirit)
The Ice Beast is no longer subject to nonlethal damage, precision damage, or extra damage from critical hits as well as gaining immunity to all mind-affecting effects (charms, compulsions, phantasms, patterns, and morale effects).. In addition, any time the target of an Ice Power that requires a saving throw fails its save, it becomes fatigued for the duration of the Ice Power (or of any additional effects on the Ice Power, whichever is longer) for a minimum of 1 round. This is in addition to any other effects.
Frozen Faculty Finality (Spirit)
The Ice Beast is no longer subject to death effects, necromancy effects, ability drain, or energy drain. In addition, targets of Ice Powers are exhausted instead of fatigued. If the Ice Power doesn't require a saving throw the target is exhausted for 1 round with no save.
This is basically Warforged Juggernaut Living Construct to Construct progression with the fatigue/exhaustion mentioned earlier and basically mixing a bunch of things mentioned in this thread minus the stat bonuses I originally talked about for Living Construct (and it needs something because Living Construct isn't good enough to match delayed spellcasting/maneuvers). It's a first draft so might not be on the nose. Feedback?
