If you've never played minions, you should learn some ground rules.
1 - Minions are NOT you!
Minion skills may be Spells, but the only Spell portion is you summoning them.
Cast Speed will create them faster, but once they exist Spell Damage or any other modifier on you will NOT affect them.
2 - Minions themselves have skills, and those are either Attack or Spell, some are Projectiles, some are AoE.
3 - Support Gems affect Minions according to the skills they use (SRS are Physical Attackers, Phantasms are Phys Projectile Casters).
4 - Minion mods on gear and jewels and anything else affect minions.
5 - Thing you apply to enemies such as Shock and Curses, do affect minions just like they would help any other ally.
6 - Minions are NOT Party Members, but they are Allies.

So SRS is actually expensive. Early on you'll have an easier time since you have less auras and more mana, and will rely on flasks mostly as well as maybe Clarity, but as you level it will quickly become clear it's an issue.

Some ways you can solve that:
1 - Unleash instead of Spell Echo (might just be smoother mapping in general)
2 - Reduced Mana Cost of Skills on Tree and Rings/Amulet (as needed), whether % Reduced, or -# Cost
3 - Flat Mana on Gear (to make sure you have enough to cast your skill at least once)
4 - Most important one is an Enduring Mana Flask. Basically, you make Mana Flask that doesn't stop when you reach full mana, and you rely on that to spam your SRS. You can either have it trigger when the duration ends, or use it manually, depends on how well you can sustain it (keep in mind the Flask Mastery we took as well - that's why)

Can we go EB? Yes. Either from Catarina's helmet, or from the actual tree. Is it worth it? Not late-game, but it could be a good crutch early if you're lazy.

In general, you level up as either pure SRS, minion instability SRS, or Absolution. All 3 options work great.

Ghazzy did a much better write-up than I can HERE:)
Ziz made some good notes on leveling with SRS here too.

In general: Grab Minion Duration + Minion Damage ASAP, and consider leveling with Minion Instability for a while (if you like) - for the Templar it means something like going straight to Witch (Starting through the Minion Damage passives), and then heading straight down to Scion from there (respec later). Spell Suppression and Armor only really matter for maps unless you're HC, so just grab Minion DPS stuff early + Duration.

If you're a Scion, grab Duration early and head up to Witch.

Explodie AG for Clearing, like Kay uses HERE

Speccing into Minion Crit late-game? Depends on 3.19 changes and PoB.
