Well, we leveled with a 0 gap from level Silkroad gold 1-40 using GT and SP Ticket. We were mostly always in parties as well, so we leveled quickly. From level 40-50 we grinded alone or was occasionally powerlevelled by our friend/academy leader. Once we were level 50, we had a 9 level gap for farming. That is when we joined the guild we are currently in and the higher levels in the guild began us.
So we could be higher level. Since we had a 9 level Silkroad online gold gap, we were able to gather enough SP to be almost full-farmed, but not quite. P Currently, our Warlock skills are up to level 60 and our Cleric skills are at level 55, which we will not update until we are level 64. But we highly recommend that you take your time and farm your character before you start leveling, you will not regret having max skills for both trees all the way.
We do not have to make a general Warlock/Cleric guide anymore. But this was only made with the knowledge we have gathered through playing this build in Silkroad. We are sure other Warlock/Clerics as you could also offer lots of useful tips and strategies that we may not be aware of yet. We believe it's best to look at more than one point of view on a subject before arriving to a conclusion.
