Courageous only gives a bonus to fear saves, not all morale bonuses. faq

Well that is good to know, thanks, and in that case I can only agree wholeheartedly on Darksol's appraisal.

Quite enjoying your guide, not sure if you're still updating, but wanted to mention that for the Courageous weapon special property it boosts all morale bonuses to anything by half the enchantment bonus.
Not sure how many morale bonuses a Fighter sees, but can be nice with either someone who has taken the flagbearer feat (a nice + half enchantment bonus to hit and dmg), or when paired with the Furious property and a friendly caster who knows Rage (a +2 Furious Courageous weapon would net you an effective +4 enchancement and an extra +2 str/+2 con and +2 to will saves). Admittedly these are more corner cases that require some teamwork, but certainly better than half enchancement bonus to saves against fear.

While I did find this guide very useful and enjoyable. I DO have to say one thing.

Unless I'm wrong, which is possible, I believe that objects always FAIL their saves against spells (with the exception of figments and glamer effects that specifically state they don't damage objects, support weight, ect.)

So things like Tiny Hut actually DO block rain, and strategies that involve shadow arrows passing through terrain don't actually work.

Damaging Objects > Saving Throws > Unattended Non-Magical Items: Non-magical, unattended items never make saving throws. They are considered to have failed their saving throws, so they are always fully affected by spells and other attacks that allow saving throws to resist or negate.

Normally true, but you'll find in Shadow Evocation, Greater Shadow Evocation, Shadow Conjuration, Greater Shadow Conjuration, and Shades the line:

Since Tiny Hut is an evocation spell, and Shadow Evocation has no confusing 20% effective thing going on, that means every rain drop would succeed at its will save and enact its cunning plan to make your character wet and possbily also cold depending on the climate.
I'll be buggered as to what a 20% effective mage armor does though.
