Launch your combo Practicing Focus Multitasking: Go to monsters you can kill in 1 hit, no matter what skill you are going to use. They should be populating a vaster area with not too few of them running around. A good example would be the Red cabal alz Garlie in Dessert Scream. Select one of them standing a moderate range. Launch your combo, time it right - your guy will walk over to the mob. You should have plenty of time to select a new mob, standing a bit off your current target. Select it and wait until the Combo Gauge starts filling again-hit the next skill and your guy should once again walk over to the mob leaving the first mob dead behind and you quite a lot of time to search for a new one. It is all a bit too much for him and trying to remember all the things he learned do not seem to work well in practice. But at least he succeeded using the Focus Multitasking. The rest will come all on its own just by using the combo skill now and then and finding suitable monsters to use it on.
