Also, is this considered a difficult DC. Like Draught of Living Death DC. ((I'm using this one because this was the potion they were expected to brew 6th year.))<br/><br/>On another rules question, How are the DCs set? Because obviously a normal student couldn't reach this DC with only 2d6. What are the average rolls? Most systems have them marked. Also, does the year you're in change the DC for spells as you learn them? Like certain spells 6th years would know, 4th years wouldn't. And certain spells 6th years simply have more practice on than a 4th year. Are DC's consistent for every character?<br/><br/>Let me know if I should just go reread the rules and if I'm being silly in asking. :)<br/></blockquote><div class="quotefooter"><div class="botslice_quote"></div></div><br/>Some good questions.<br/><br/>Admittedly, the DC is high, but that is because the things that make potions tricky in the setting are hard to simulate.  The first, ingredients, are rarely a factor.  We don't really keep track of expenses or the gathering of materials.  The second is the time to brew, which is largely done behind the scenes.  The third catch is failure.  If you fail to brew a potion, you know (because you rolled) and can choose not to drink it, and avoid the consequences.  A spell, on the other hand, punishes you instantly for failure.<br/><br/>This reminds me of something I need to state in the rules thread.<br/><br/>Also, brewing a potion under the watchful eye of a professor does grant a +3 bonus.<br/><br/>"Normal" is a difficult term.  After all, no one in Hogwarts is normal.  A rating of 2 is an average person without proper training, so most spells can not be cast with a 2, as most require very precise motions and inflection.  With a 3, you will succeed on basic spells (DC 9) far more often than not.  3b1 gives you a 50% chance on DC 12 spells, so some of these are not quite as difficult as they seem.  Hell, Xavril just cast a DC 17 with 4b1.<br/><br/>As for familiarity, I kinda let this one slide.  If I catch a 4th year player constantly using obscure spells or making up their own (a concern of late after the confetti spells), I will say something, but there are no hard rules.  DCs may change on situation, but not person.
