Beast Mastery/Storm Summoning

How about this as a character build, Magic origin with Beast Mastery with Storm Summoning

That tells us nothing. Try using mids to give us an idea of what you want and I'll give a shot at improving it.

As storm summoning goes though, I dunno. Melee pets and lots of knockback doesn't exactly synch well.

But there IS a good deal of synergy to the two if you take time to find it.

KnockBACK may suck, but knockDOWN is actually great for pets. So that being said, you can wipe out entire spawns by leading off with a Freezing Rain and turning your pets loose with the occasional O2 Boost.

Here's the kicker, though. Beast has no pets that can use the Recharge Intensive Pet IOs. Storm lets you slot them in Tornado.

So you can theoretically slot both +Resist and +Defense IOs, as well as the +15% AoE Defense ATIO. I put them all into Tornado as a mule, and then slotted full Blood Mandate sets to cap my own Defense out as well. Your pets are getting +20% Resistance to all damage, +10% Defense to all, and a bonus +15% Defense to AoE doing that.

Add all the IOs to your control in Freezing Rain, the buffs from Steamy Mist, your Minion-level lockdown from Thunderclap, and your spot-heal in O2 Boost, and Beast/Storm is a pretty damn strong setup.

It's active, though. This isn't Bots/Force Fields by any means. If you miss a power activation or time things badly, you can and will get yourself or your pets killed.

That being said, nothing but Nemesis with stacked Vengeance really gave me problems.

I have FINALLY managed to get the SE to drop a KB to KD proc, and so yes, I am really rethinking how I use Tornado.

Means the pets will be squishier, but knocked down and dead things don't do them any damage.
