At level 9, your pulse for deploying jumps by 3 (+1 max pulse, -2 deploy pulse cost). Also, just pulse and class features in general. Roughly half your potential pulse comes from class features that modify your pulse, rather than your base pulse. If you're willing to wait or you can manipulate your Wisdom checks, you can use Channel Ley for another +4. Makes it a stupid good boost for prebuffing, I guess. Really, though, pulse is weird. It scales realized plans' areas stupidly, but otherwise it's a minimum requirement for deploying plans, an expended resource for flaring, and the thing that controls plan duration. The actual strength of a plan's effect is based on your skill checks, which, while related to level, aren't solely dependent on it. I expect you're going to get a lot of Truenamer-style optimization of skill checks to hit the highest power you can get, but... I dunno.
It takes 10 pulse to realize a plan with a radius ~4.5 times that of Earth. You can do that at level 15 if you have a +10 Wisdom check modifier and take 10 with Channel Ley. If you find a way to get the boosts from Coalesce Ley Web to apply to a realized plan, you can roughly cover the galaxy with 25 pulse. Exponential growth is fun, am I right?
Alright, now that we've covered the entire planet with a realized plan, what do we do? Grab a bit of fire resistance, then use Heatwave. Assuming a very tame DC 30 check, you're dealing 2d8 fire damage per round for 600 rounds to everything on the planet (save for half), an average total of 5400 damage. Congratulations on destroying nearly all life on the planet at level 15.
... Mind you, that's the only thing Heatwave is good for. Deploying it is useless, since any creature that can't move out of a 30 foot radius in 1 minute is already defeated. Flaring it is just a poor blasting spell that also hits you and your allies. If you could optimize your Craft check to get enough damage to be useful at low levels, you'd be one-shotting yourself, too.
Broken Ground is a no-save immobilize for non-flyers. It costs 1 more pulse to realize than Heatwave, but if you want to wait to level 18 instead, you can make the planet permanently unlivable. Also, the Flare effect is more powerful the lower your check result is. All a high check result gives you is the potential ability to not be affected by your own plan (along with letting your enemies ignore it, too).
Actually, on to plans in general. They're all centered on yourself. Worse, they're emanations that follow you. There is exactly one creature guaranteed to be hit by the full effect of any debuffing plans, and that's you.
