Eidolon summon:

Once attuned you can summon via action your eidolon once per day. Twice if allowed a short rest.
Mount will stay in play for three hours, until dismissed, its hit points reach zero, or is banished via spell.
If the eidolons hit points reach zero it will not die, but cannot be resummoned until a long rest has been had.

Eidolon come in ascending levels of silver, gold, and platinum as reflected by their jewelry. Silver and gold, while not inexpensive only require attunement once acquired. Platinum eidolon require attunement
as well as a bonding process each day for ten days <when first summoned for that day>. The premise being they are intelligent creatures and require some convincing to be of service.
A 1d20 plus the characters highest stat modifier must beat the eidolons highest stat. A failure will result in only no summonable refresh after a short rest and whatever penalty is described per creature.
A critical failure of a nat 1 will result in the creature dismissing itself entirely until a long rest is had.
Each success stacks till ten is reached, once ten has been reached and as long as the eidolon and riders alignment match no further checks need to made. However if their alignments do not match rolls must be made in perpetuity.
Once fully bonded a platinum eidolon will gain a bonus as listed per each individual.
