Good day!
I've a few questions which have popped-up over time, yet their answers were either not discernible or of questionable resolution.
If you're feeling up to it, please have these a go. Sources would be great!
Spells with attack rolls
1. I recall reading somewhere Weapon Focus (Ray) was a valid choice. In the case this is true, is Weapon Focus (Ray) also a valid choice?
2. As in #1, could the feats be applied to melee touch attack (MTA) spells? Such as Weapon Focus (Touch). It's a bit kinky, albeit confusing.
3. Not restrictive to the scenarios posed in #1 and #2, do abilities such as Inspire Courage boost the damage of ray/MTA spells?
4. Do boosts to damage (perhaps from sources as per #1 and #3) from rays/MTA spells include ability damage?
5. Specifically, when is a held MTA spell discharged? On a sleeve if your finger brushes by it? On the hilt of a two-handed weapon? On tangible "objects" such as aqueous orb/wall of force?
Requisite wording
6. I saw numerous contradictory answers regarding the following question: Do half-elves (for example) fulfill the requirement of being "human" and/or "elven" for the purposes of taking feats that require one of those two races, traits that require one of the two races, or archetypes that require one of those two races?
7. As an extension of #6, would abilities/effects that target a race (not subtype) of partial ancestry to the target function as if that target were of that race?
8. Does the ability to cast spell-like abilities of a particular level qualify characters for certain prestige classes that require "Ability to cast spells of X level"?
9. Does proficiency in weapons such as "Longbow" or "Whip" extend to a more specific type, such as "Longbow, Composite" or "Whip, Scorpion"? Does the reverse apply? I ask mainly because while the inverted comma notation is used there, we do not have "Sword, Short", "Sword, Long", and "Sword, Bastard"
10. Is combining archetypes with "selective" alterations to abilities (such as a vivisectionist's choice to take a bleeding attack rogue talent instead of a discovery) and archetypes with "mandatory" alterations to abilities (such as the Preservationist's Bottled Ally VI replacing the discovery at 18th level) valid?
General
11. Can a snag net be used to trip an entangled "flying" creature if the creature is plummeting (perhaps due to an effect such as entanglement)?
12. For exactly which d20 rolls is a natural 1/20 considered automatic failure/success?
13. Can abilities such as the versatile evocation power of the admixture subschool be applied to spells not of their parent class?
14. How many rerolls can a creature under the influence of a cackled fortune hex chose to take? In essence, what does "benefited" mean?
15. As full plate encases nearly a humanoid's entire body, does it grant improved cover?
16. How large does an object need to be to grant partial cover? If it is with respect a creature's size, is this comparison made with only the surface area of the creature visible to the target?
17. Could an internal alchemist "sleep" for 1000 years via breath mastery?
18. Is it possible to have a caster level higher than a character level under certain circumstances, such as the Sorcerer's Arial bloodline?
19. How good (or evil) of an act is using a merciful (as per metamagic) disintegrate spell to "incapacitate" a foe?
The last one is a doozy:
19. Suppose the following centaur-like creature possesses the following:
2 arms wielding a greatsword
2 additional arms via alchemist discoveries wielding daggers
2 hoof attacks
1 bite natural attack
With a BAB of +8 (with other melee modifiers totaling +0), multiattack, TWF, improved TWF, and under the effects of haste (whose bonus to ATK is negated by other modifiers), what are:
A. The maximum # of total attacks able to be performed in a round?
B. How many of the attacks in A are natural/manufactured?
C. What would the attack bonus on each of the attacks in A be?
Many thanks!
