Rules Questions


Can a synthesist still cast from his spell list the summon monsters or from scroll/wand/ other clickie ?

And can a sythesist use summon monster 3 , as he has summon monster 2 at lvl 4 and gets summon monster 4 at lvl 7 . i am talking about his spell list not his SLA wich he cant use while the eidolon is active

No Summoner can use their SLA Summon Monster while the Eidolon is out. It's fine to cast the spell, however (with it's short duration).

That said, are you sure you want to play a Synthesist Summoner? This archetype is banned at many tables (mine included) for reasons like this and this.

Personally I advise you just pretend this archetype doesn't exist.


my synthesist is a bipidal form not the quad form so it wont benefit from the pounce , my synthesist is merely for tank purpose and support .. yes atm i do more damage then our paladin , but as we fight in mythic campaign near the world wound ..i do intend to take the celestial form to stage 3 and be large .. this eats alot of my points

The reason i asked about the summons is , i like the archon lantarns , when i get to lvl 7 , the spell will call 1-3 lantarns , the extra fire support only lasts in rounds but the rays of light will shine in our brightests night m till no evil will remain in their sight

Lantern Archons are 3rd level, and can thus be summoned by Summon Monster III. Lantern Archons are great! While they do a bit of damage (which cuts through all DR) with their touch-attack light beams, they ALSO have at-will access to the Aid spell. I.e. Lantern Archons can add ~8 temp hp per round to anyone who doesn't have temp HP. This is often a more effective action than attacking.

So long as you play your synthesist as support and don't steal limelight from other PCs it ought to be OK.


hope so .. group of 6 paladin . cleric . warpriest . a mage/thief . a witch and a synthesist


Synthesist is generally weaker than the base summoner, because it loses action economy. Its only real balance problem is that it breaks point buy. If your group doesn’t use point buy, it should be fine. If your group does use point buy, then you’ll need some special cases, like the synthesist is forced to use the heroic array instead.

My preferred synthesist build is a bipedal reach build. You can cast spells on your turn and get some attacks of opportunity during the enemy’s turn. Reach+push is particularly funny because you can push an enemy 5 feet back and then end a turn with a 5 foot step back, forcing the enemy to use a move action and eat another aoo just to get back into melee with you.


atm my slam does indeed have reach and bleed , should it be needed , i have the spell long arms as well
