Summoner Spell repertoire at level 5?

[Grumpus]

I have a player who use a Summoner, and i was trying to understand how they get spells.

As I understand it, at level 4 the summoner should have 3-1st level spells known and 2-2nd level spells. Giving the maximum of 5 spells.

At level-5 it says you add 2 level-3 spells, (bringing you to 7 spells known) BUT that you lose your lowest level of spell slots and 2 spells form the repertoire. So i assume the 2 you lose would be 1st level spells. So now that leaves me with 2-3rd, 2-2nd and 1 useless 1st level spell known. What are you supposed to do with the spells of levels you can't cast anymore?

Do you have to have a useless spell until level 6 where it says you can swap spells then?

Hopefully this makes sense, I am sure there's a thread a couldn't find or maybe a better explanation in the book someone could point me to.

All of a summoner's spells are signature spells. They can absolutely still cast lower level spells by heightening them to a level they have spell slots of.

Yep, basically just make sure at least 1 of your level 1 spells known is something you still want to be casting at level 5+ (ideally, but not necessarily, something that you're cool and happy to heighten).

Common picks might be Soothe, Heal, a damage spell, etc.
