The game is not that hard. Really. New game plus is a different story, but you're already experienced by then.
I played a Royal my first time through it. Reached Soul Level 100. Wiki was VERY helpful.
My Royal was heavily focused towards Magic, with spells like Firestorm, Soul Light, Death Cloud, Acid Cloud and Poison Cloud. I also got Thirst from Yuria to help me with the Soul farming.
At level 100 my Royal is Vit 24, Str 22, End 30, Mag 30, Will 30 ...those are my major stats, the others were very neglected.
Armor: Old King Doran's set, Talisman of Beasts, and (as of now) wielding Soul Brand for 500 damage (still haven't reached the part in new game + when I can forge North Regalia)
Shield: Dark Silver Shield +1
On my first playthrough I didn't get any Pure White World, but got two Pure Black ones, killed Satsuki Phantom, and Killed Scirvir. I also got Pure Black Character tendency (hence my 500 dmg from Soulbrand) and did the Mephistopheles quests that were available.
I also started playing a Knight, heavily focused on melee combat.
As of Level 77 he is:
Vit 27
Will 15
End 33
Str 30
Dex 17
Mag 10
Faith 16
Luck 9
Turned all worlds to Pure White except 5 which I still haven't beat. Beat Miralda in Pure White, and Satsuki, got Makoto, got Rydell's and Scirvir's presents.
Able to cast soul arrow, total protection (twice), Anti-magic field, and other resourceful miracles like Cure and Evacuation.
Weapon : Meat Cleaver dealing around 370 dmg right now.
Also got Keel Smasher, but I don't like it....and too heavy for me right now. I'm looking into leveling up Makoto with Colorless Souls.
Armor: Yurt's armor set. And I replace the legs and the torso parts with leather/black leather armor if I need agility. For the most part this character plays most the time over medium equip weight.
Shield: Dark Heater Shield +3/ sometimes Purple Flame Shield.
This game is at 25 hours of gameplay right now (my 100 level royal took me 58hrs. first time through).
QUESTION:
1-What is the best piece of equipment to upgrade with colorless demon's souls?
2- Is the insane catalyst all that better than the other catalyst/talisman of beast?
Thanks. I'm open to any questions, I love this game, we should hype it a lot more, just like people did with VC around here!
