Det finns en FAQ relaterad till detta:

Summoner: If I choose the reach evolution for my eidolon, how many of its attacks gains increased reach?

The ability description says "pick one attack," not "pick one attack type." So if your eidolon has two claws and you pick "claw" for the reach evolution, only one claw gets increased reach. (The reach evolution is intended to let you emulate having a dragon-eidolon, as a dragon's bite attack has greater reach than its claws.)

Om vi extrapolerar det ut, om du har 4 tillverkade vapen skulle bara ett sådant tillverkat vapen nå räckvidden, även om de är alla samma vapen

Obs! Denna FAQ gäller för den kedjade samtalaren, även om jag anser att den fortfarande är relevant för ochained, med tanke på Reach evolutionen för både kedjad och ochainad är formulerad exakt det samma. Så, frånvarande någon särskild formulering någon annanstans för den ochained eidolon, skulle jag säga att avsikten är densamma, och denna FAQ gäller.

Bara märkte detta medan man tittade på möjligheterna och kände att det var värt att påpeka.

Ge din eidolon en storleksökning, så att den når alla angrepp!

Large (Ex)

An eidolon grows in size, becoming Large. The eidolon gains a +8 bonus to Strength, a +4 bonus to Constitution, and a +2 bonus to its natural armor. It takes a –2 penalty to its Dexterity. This size change also gives the creature a –1 size penalty to its AC and on attack rolls, a +1 bonus to its CMB and CMD, a –2 penalty on Fly skill checks, and a –4 penalty on Stealth skill checks. If the eidolon has the biped base form, it also gains 10-foot reach. Any reach evolutions the eidolon possesses are added to this total. The eidolon must be Medium to take this evolution. The summoner must be at least 8th level before selecting this evolution.

If 6 additional evolution points are spent, the eidolon instead becomes Huge. The eidolon gains a +16 bonus to Strength, a +8 bonus to Constitution, and a +5 bonus to its natural armor. It takes a –4 penalty to its Dexterity. This size change also give the creature a –2 size penalty to its AC and attack rolls, a +2 bonus to its CMB and CMD, 10-foot reach, a –4 penalty on Fly skill checks, and a –8 penalty on Stealth skill checks. If the eidolon has the biped base form, its reach increases to 15 feet (10 feet for all other base forms). Any reach evolutions the eidolon possesses are added to this total. These bonuses and penalties replace, and do not stack with, those gained from becoming Large. The summoner must be at least 13th level before selecting this option.

Medan räckvidden ensam ger det inte till alla dina attacker, kan du göra din eidolon stor eller stor för att ge den 10-15 ft räckvidd!
