Berserk spells
Battle focus

(Self buff) This increases the user's concentration in combat, allowing them to pay more attention to their opponents. It also makes the user's spellcasting more difficult to interrupt. Overall not something to overlook while fighting, and hopefully remember to be used in more extreme fights.
Additional information
Incantation: "Refine the detail, overlook nothing and without hindered actions."
Active sign: Eyes glow faintly and heightened senses.
Advantages: Able to remain calm and see the entire picture while fighting, great for fighting off groups or noticing weakness and exploiting it.
Dis-advantages: Very hard to master, and even harder to maintain for those with hair trigger emotions.
Mastery Refinement: Within spoiler.
0-29 beginner: Psst... your fucked.
30-99 novice: If they give you a minute or two you can focus, but one hit taken and you lose it, sorry.
100-199 trained: You still take some time to get into the heightened state, but good news you can take a few blows before you lose it.
200-499 proficient: Don't get Cauchy yet, you still take time to get into things but losing focus ain't an issue anymore.
500-999 adept: A few seconds and your in the zone, but you cant keep it up for long anymore it seems.
1000-1499 expert: No time to enter into focus mode, and while you can hold it some time you know there is still more to go.
1500-2999 mastered: Much more detail while you focus and time extended. But the peek is still higher.
3000 illustrious: Focus on the flip of the dime, all the time, any time. Your the best and nobody but those on your level can really tell you otherwise.

Adrenal Rage

(Self buff) Tapping into pain and converting it into increased strength and focus to deal more dangerous strikes and spells to those when needed. Sometimes weaker then others but with increased pain the greater pool to tap into, do be careful when hitting this person.
Additional information
Incantation: "Burn the eternal ember."
Active sign: Faint reddish-yellow aura surrounds the user and their weapon.
Advantages: More damage, more ass-kicking.
Dis-advantages: Need to be hurt to tap into it.
Mastery Refinement: Within spoiler.
0-29 beginner: You would need to be on death's doorstep before you can give them a good last swing.
30-99 novice: Maybe your on death's lawn when you get a swing or two of some greater force.
100-199 trained: Your looking at Death's white picket fence, but you swing like a monster while he drags you into his house.
200-499 proficient: You get down to maybe half hp before you can start unloading the real power you let build up.
500-999 adept: Just a little less to get you at your A game fighting power.
1000-1499 expert: Maybe seventy-five percent health you get your stronger strikes. But you hit like a bus so, least it won't go down much further... hopefully.
1500-2999 mastered: It does not take much to draw out the full power you can get, but there is still the fact you need to take some damage to get swinging.
3000 illustrious: Someone tickled you, HULK SMASH!
