Erebus looked on as Ethan-Jason attempted to conjure a spike from his palm.
"Growing spikes from off your body isn't too hard. Just think of where it's gonna grow from, how tall/wide you would want it to be, and that's pretty much it. Same with shooting spikes. The key there would be to keep them small and thin (but not needle thin). This way you won't use up a lot of strength or hinder your aim with shooting giant spikes from your wrists. Also, shooting smaller, thinner spikes create less drag, thus making them faster projectiles that inflict more damage then they would as stationary weapons." Erebus explained, taking a metaphorical breather before continuing.
"Then there's raising spikes from the ground. The same rules apply for these as well (think of where you want them to come from, and presto, insta-spikes). You could have grow straight up, in one spot (to entangle, impale), or you can have them blast toward the opponent in a diagonal angle (to pin them against something, impale, and look awesome and intimating). You just have to be in contact with the ground that you want the spikes to come from. Also, I would advise you to not do this inside the Promenade, because the spikes will leave holes all over the ground. Also, along with not getting angry, don't get too involved in the fight, because all the excitement could merge into anger. If you find yourself becoming way too vicious in your attacks, then break away, fall back, and take a deep breath." He finished, crossing his arms.
"So, is there anything else you need to know about?" He asked.
