New item creation feat for summoning creatures

[Shain Edge]

I would like to throw this idea of a Feat out to see the response it gets as to power level and usefulness.

Bind Summons (Item Creation)
Prerequisite: Able to cast Summoning Spells like 'Summon Nature's Ally' or 'Summon Monster'
Character is able to invest the time and resources to bind an outsider that suits the needs of the caster. The creature can be no more powerful then the creatures from the summon spell that it is linked to. This feat effectively extends the caster's summon list.

Any creatures who are bound with this feat are unique individuals. If Summoned more then once in a day, they will continue to have any damage that was inflicted on them. If killed, that creature is unbound, and no longer available to the caster. The creature is assumed to heal all damage at the same time the caster rests to regain spells.

Summoned creatures from this feat are unable to take new or leave items behind. Any items removed, such as being disarmed, will leave along with the summoned creature.

Creatures may be 'upgraded' similarly as magic items. If upgraded to a higher CR, they may only be summoned by the new level of spell, and no longer by the old level. This upgrade may be the creature becoming tougher, or may have better equipment that increases their CR.

The cost is equivalent to making a scroll with the level equivalent to the level of spell used to summon the creature.

A few more feats to further define creating creatures for summoning. It also introduces a ladder effect. If the caster is of a divine background, it is easier to learn to summon creatures able to use divine abilities and spells, but with another feat, the caster can then learn also to summon those who can cast Arcane magics. The opposite is true with arcane casters. Easier is the ability to learn to summon those who can use arcane powers and spells. More difficult is to learn how to summon those of divine powers and spells.

Arcane Summoning (Item Creation)
Prerequisites: Bind Summons Feat and either the use of arcane Summon Monster spells or already having the feat Divine Summoning

Description: Creatures you bind with Bind Summons Feat are able to cast and use arcane abilities, such as spells. It is possible for creatures to have Character Levels in Sorcerer and Wizard for example. The level of the Summon Spell must now take in account the ability to cast spells.

Normal: Creatures you summon are not able to cast spells at all.

Divine Summoning (Item Creation)
Prerequisites: Bind Summons Feat and either the use of divine Summon Monster spells or already having the feat Arcane Summoning

Description: Creatures you bind with Bind Summons Feat are able to cast and use divine abilities, such as spells. It is possible for creatures to have Character Levels in Druid and Cleric for example. The level of the Summon Spell must now take in account the ability to cast spells.

Normal: Creatures you summon are not able to cast spells at all.

Seems interesting but would probably just be easier if you left it as a Craft Wondrous Items sort of thing.

Like I could create a half red/half white use activated item. To use the item one must throw it and say, "I choose you *insert type of creature to be summoned*." To hit a specific square with your Summon Ball you must hit an AC of 5.

A Summon Ball I can be created with Summon Monster/Natures Ally I, and would cost around 2000gp and would only last a round.
A Summon Ball n can be created with Summon Monster/Natures Ally n, and would cost spell lvl*caster lvl*2000 and would last a number of rounds equal to caster lvl.

Alternatively you could have the item be continuos (same price as use activated*4) and just have these creatures follow you around all day long. Then it can have some rules like the following: If your creature is ever dismissed or killed it will appear 1 round later. You may choose what it will reappear as depending on what is available for the given spell it was crafted with.

Edit: And you can use the summon ball as many times as you want, just make sure to pick it up after you use it.

Extended summoning time feats work around the premise that summons can last a lot longer then a minute or two. In fact, some summons can potentially last years. One feat which has a progressive meta-magic quality can be used to create this effect. Higher level casters have the option of casting spells for extremely extended durations, at a cost of weaker summonings. Summoned creatures who are reduced to 0 or below HP return to their plane of existence.

Extended Summoning (Meta-Magic)
Description-

Basic ability: At 0 spell level casting adjustment, the spell has a duration equivalent of a caster one level higher.

Using the Extended Summoning feat at +1 or more to Spell Level adjustment requires prepared materials which have the equivalent cost and time to that of creating a spell scroll of the adjusted spell level. These materials also require an extended preparation and casting time to use. While there are creatures summoned by using this feat, this feat is unable to be used for additional summons.

+1 Spell Level to change rounds into minutes. It takes a full minute to cast, and takes a full minute to complete preparations and casting.

(Additional) +1 Spell Level to change minutes into tens of minutes. Takes five minutes to prepare and cast the spell at this level.

(Additional) +1 Spell Level to change tens of minutes to hours. Takes a half an hour to prepare and cast the spell.

(Additional) +1 Spell Level to change hours to days. Takes a two hours to prepare and cast spell.

(Additional) +1 Spell Level to change days to weeks. Takes eight hours to prepare and cast this spell.

(Additional) +1 Spell Level to change from weeks to months. Takes a week of preparation and casting.

(Additional) +1 Spell Level to change months to effectively permanent, even beyond the caster's life, though will still be returned to their plane of origin on reduction to zero or below HP.

Hehe. That is a good one. To be honest I didn't even consider that aspect of 'summoning'. But I guess it could fit!

I'm actually considering that there should be a material component to Bind Summoning. A scroll that effectively contains the contract of binding. Anyone who has this contract can use their own power of summoning to summon the specific creature.

If the contract is destroyed, the creature is no longer bound. If the creature dies/becomes unbound, the contract flames to dust.
