> throwing aim
You hold the direction after Kratos grabs him, should work. The timing is a bit finnicky. It only works on ground-to-air.
> roll trap
A lot of the common mentalities will see you dead here for real.
> sirens
The camera is a tool you can use to keep foes off-screen. Enemies CANNOT attack off-screen and will cease any animations they are doing if they go off-camera.
> petrify
Wait until God of War II where you get a giant-ass hammer that nearly OHKO's petrified enemies.
> magic
They have their uses. Lightning isn't that great imo, but you can use the 'grab lightning' startup animation to cancel a ton of your animations. Poseidon should always be done in the air (less recovery) and is more of a screen-clearer. Hades (you get that one a tad later) is busted beyond repair. If you max that one out you can kill the final boss in like 3 casts haha. I feel magic was still in its infancy here, GoWII really upped the bar on that regard.
> Taz makes you feel shame
Wait till you reach your boy roy (hahaha). Nawh Taz is absolutely fantastic. I also highly recommend Bick's runs and Shinobier. Wolf(?) is also great.
> rolling forever
You can cancel the roll animation with a regular light-attack, then cancel that attack with another roll, completely removing roll-recovery.
> the legendary SST meme
I honestly have no clue. The game can be pretty fucking brutal on Normal already, let alone higher settings. I cannot imagine playing this game with SST spam. What most do is just SST, then dodge back and SST again. This CAN work, but it's super tiring and takes forever as you're generally just chipping enemies out with the splash-damage of the plume.
