Introduction
This is my preferred approach for taking Heirophant through the campaign. This approach scales nicely into Wander w 
Power Siphon and 
Ballista Totem Support (I run this and make $$$ then swap over to 
Mjolner after assembling some currency).
=============================================================
The Mule
I find 
Rolling Magma to be an incredibly not enjoyable skill to use (and I see that many agree). So here's what you do instead.
Roll a Ranger, grab 
Caustic Arrow at town, and grab an 
Iron Ring.
Go finish the first two relevant quests ("Breaking Some Eggs", which is the Rhoa quest in the Mud Flats is required, and then "Mercy Mission", which is grabbing the Medicine Chest on Tidal Island).
Go to vendor to buy the shopping list. Any extra $$ you have you can snag more Iron Ring or buy a Wand.
Shopping List:
1 - Grab 
Kinetic Bolt which is an enjoyable leveling skill and wand-based, and old man can't get it to start
2 - Grab 
Sniper's Mark which Old Man does not get access to for a long time and really helps beefy boys
3 - Grab 
Momentum Support for our 
Shield Charge, which again Old Man doesn't get until A3
4 - If you finished Mercy Mission you also get an additional 
Quicksilver Flask, which is great because the Old Man is slow AF
** This process takes about 5-10 minutes and makes the next 2 hours MUCH better and potentially saves that time back + some if you do it right.
=============================================================
The Old Man
Okay now we're ready to roll the templar, grab all the muled gear, and fly.
In town you can buy 
Prismatic Burst Support to socket with Kinetic Bolt which is VERY nice early on.
By the time you get to Level 4, you are decked out with:Kinetic Bolt + Prismatic Burst Support
Holy Flame Totem + 
Summon Phantasm SupportShield Charge + Momentum Support
You also have 
Frostblink, 
Flame Wall, and Sniper's Mark
If you did everything right you also have: 2x Quicksilver Flask +2x Iron Ring
Old man is ready to rock
=============================================================
From here, you will scale into the links I have in Pre-Swap Variant.
Post-swap after Act 3 Library depends on what you are building.
Palsteron's is best for Totem + Wand Power Siphon imo: https://www.youtube.com/watch?v=WhVwjbJD8_U
Personally, I'll be following Palsteron until I have the $$ to swap to Mjolner. Switching to Mjolner early can be brutal for speed and survivability, and big scaling tiers are $$$, so I like to wait.
I am newer to POE1 scene, have a lot understood but still super DS in many ways... with that I'll be updating this guide for that progression as I go.
