Q438 Does an alchemist with Wings discovery get half his level added to Fly checks when using the ability to fly? Technically it says it works as the fly spell but it's an extraordinary ability with actual physical wings and no effective caster level. And does he fall slowly if he uses up his entire duration?

Pathfinder devs really need to get their **** together. There's Sp abilities that aren't based on spells and Ex abilities that are copying spells. It's ridiculous.
