1) pages, chance to get one while leeching is about 50% + we have a purple box for getting some honour (idk exact values, but that can give a 1-3 pages, sr/ssr books etc). When you host - you get a 3-5 when not mvp (excluding a purple box). Och host is 1/day as i know.
And you can buy some pages in shop too. Oh, and you can get a complete book, but chance is VERY low (I still don't have any).
2)fangs - you can trade 10 per week on DMM + we just got a 2 new tier of sp quests on DMM - ultimate + that is 50 ap and has a guarantied fang + chance to get more and ragnarok that is 1/day, 90 ap and has FIVE guaranted fangs so it's much easier to get fangs nowdays. But you shall suffer next year with this fang drop on nutaku. It's possible to get 150 fangs for t4 soul in 2 days easy, especialy with half ap campaign, that is now at DMM, I can approve it. Only pages are still hard to get.
3)t2cores - do daily experts, trade t1 into t2, it's the easiest way, do ultimate daily if possible .I don't like drop in standarts so I skip them.
