Ok I am not going to make a formal guide but I will give ya some basic things. First of all as soon as u become a beggar keep the basic beggar's footsteps and basic beggar's meditation on at all times (even if it makes u meditate a lot cause mana gets drained too quickly). After that when u actually become a vanguard beggar then u will get extra cool stats.
kk this is how to raise chi
+2 STR
+1 CON
+1 DEX
Keep on doing this and as long as you have beggar's footsteps and meditation on you will do just fine
Also when you gain a new martial art do not adjust to it right away. You have to adjust to every second martial art so for example you get a new martail art and you make it ur primary art and use it. Then u level and new martial art appears (do not adjust to it) you should not make it ur main martial art don even bother to learn it. Just wait a bit more and learn the next martial art that apears that way ur attack will be stronger and you won't have to waste useless time ^^
