What root should I be using
 

Newbie-ish 48 Shaman here. I have been using my lowest level (19) Root spell for a while. Enstill costs a bit more mana and is a longer cast, but I'm noticing it breaks very often. I decided to keep using my 19 Root spell for efficiency purposes. Mostly root rotting and using slow with pet.

Am I doing it wrong?

Keep doing what you're doing until paralyzing earth

^^^^^^^^^^^^^^^^^^^^^

Use "Root" until you get PE.
Enstill isn't worth the mana given how often mobs break root on server ticks(ever 6 seconds) here. You could litterally cast root and 1ms later a server tick happens, root break formula is checked and failed, mob breaks root. It's a nightmare. People have theories about different roots working different ways, but the sure fire route is Root -> PE. Skip enstill.
Get your level up, Don't grind mobs that have high MR.

Immobilize at 51 is better than Enstill but it's still not worth it to be brutally honest.
Paralyzing Earth is level 56, cost 100 mana and lasts at full length 3 minutes.

I have a theory that things like root breaks and charm breaks on p99 are coded to be more difficult thus giving a more hardcore classic feel to the server. I can't tell you the number of times I've had and seen roots/charms break back to back to back. I always say afterwards I wish I recorded that, It's beyond stupid.

Thanks for the tips. Does Malisement help with root lasting longer?

Anything that lowers the targets magic resist will help. That's not to say that it will gurentee they don't break root. But yes it will help, I malo targets who are prone to breaking.
This is also very situational. You have to factor in your mana, add chance, surroundings, etc.

Also I know what you meant but based on how you worded it, to avoid confusing anyone. It won't make your root spell last longer but should help make sure that it lasts it's full duration.
Every 6 seconds on the server it runs the root break chance formula while a mob is rooted. Magic resist is in fact a part of that formula. The level of the person casting root may be a factor.

Thanks Baler. Onward to 56!

And thanks to GinnasP99 for starting off with solid advice! :)
ps. Using shm pet against a slowed target can be very effective. As long as you're not resummoning your pet often or at all, those buggers cost a lot of mana. And they do add some extra dps.

Can confirm that Paralyzing Earth is OP

You should use the best root you have. always have regen and sow on and if your low on mana you cani for it. I have done 3 cycles on a mob could have done 4 if needed. the cycles go like this;

pull with slow
1st dot (disease)
2nd dot (poison)
root

cycle 2
2nd dot
root

cycle 3
2nd dot
root

should be dead by now if not

cani till root breaks
1st dot
2nd dot
root

not dead yet
run away this is going to kill you :)

can confirm, enstill a poopy spell. it break a lot and cost more, so do/did not use.
