So the Phase Shield has a capacity of 40 and a usage of 2 but no duration on the usage. Same with the Titan Shield which has a capacity of 40 and a usage of 10 but no duration on the usage. How long do these items continue to operate? Are they use once and gain a constant effect until disabled? If so, that just boggles the mind and defies physics. Can i leave a titan shield on forever?

I have a level 10 wizard and I am considering building a Homunculus using the Craft Construct feat. I have some questions regarding the rules, primarily

1) How many HD can it have maximum? Is the Homunculus limited in its HD by size and/or HD of my wizard?

2) How many feats can it have based on HD? Which feats would be available (monster feats only or all feats)?

Also, does anyone have experience with building constructs in general or specifically a Homunculus, and what advice would you give regarding design?

My wizard already has a familiar, so I am building the Homunculus as a second companion, rather than as a familiar.
