What rules do you use for familiars. The basic rules as written for 5e seem a but limited. I have been working on some homebrew options, and came up with these two feats. Thoughts?
Familiar, Combat
Prerequisites: Ability to acquire a familiar via spell or class ability.
[FONT="]• [/FONT]You can use your reaction to dismiss your familiar to its pocket dimension. You can summon it again as a bonus action.
[FONT="]• [/FONT]Your familiar has half its master’s total hit points (not including temporary hit points), rounded down, regardless of its actual Hit Dice.
[FONT="]• [/FONT]Your familiar uses its masters base proficiency modifier for attacks, saving throws and skill checks.
[FONT="]• [/FONT]Your familiar gains the improved evasion ability. When subjected to an attack that normally allows a Dexterity saving throw for half damage, the familiar takes no damage if it makes a successful saving throw, and half damage even if it fails the saving throw.
Familiar, Improved
Prerequisites: Ability to acquire a familiar via spell or class ability.
[FONT="]• [/FONT]Your ability to summon a servant creature such as a familiar is enhanced. You can now summon a tiny or small creature of up to CR 1 (for possible familiars see Table below).
[FONT="]• [/FONT]As the master of a servant creature such as a familiar, you can choose two (2) of the following familiar traits. If you are a warlock with the pact of the chain class feature, you can choose one additional trait.
NOTE: When you cast the find familiar spell for a standard familiar, you also gain the boon for the familiar you summon.
[FONT="]×[/FONT][FONT="] Boon. Your[/FONT] familiar bestows a special boon upon its master. This ability is variable, and depends on the type of familiar.
[FONT="]×[/FONT][FONT="] [/FONT]Superior. Your familiar’s ability scores each increase by 1.
[FONT="]×[/FONT][FONT="] [/FONT][FONT="]Telepathic[/FONT]. You are considered to be in contact with your familiar for the purpose of shared spells, as long as it is within 1 mile of you. You and your familiar can communicate with each other telepathically at a range of up to 1 mile.
[FONT="]×[/FONT][FONT="] [/FONT]Tough. Your familiar gains +1 hit point per character level.
