Ok let me tell you how to use my chart (updated one is
<< here >> )
When you connect 2 WS together, you will get a Lv1 Renkei effect same as the later WS, or Lv2 Renkei. You may connect with another WS for chain Renkei by follow chart direction.
Lv2 and 3 are same principle.
example.
Player1 does
Fast blade (Scission)
Player2 does
Burning blade (Liquefaction, piority over Detonation)
Liquefaction Renkei lv1 created (Magic burst with Fire)
Player3 does
Combo (Impaction)
Fusion Renkei lv2 created (Magic burst with Fire/Light)
Player4 does
Blade: Ten (Gravitation)
Gravitation Renkei lv2 created (Magic burst with Earth/Dark)
Player5 does
Cross Reaper (Distortion)
"Dark" Renkei lv3 created (Magic burst with Water/Ice/Earth/Dark)
Strahd your mistake was: you need to use another "WS" connect to Renkei to create another "chain" Renkei. Hope my example make it clear for you.
