Well, I play the obvious Matuvu - Green Gem Combo in the first area. In the Warehouse I play the second of the Matuvu - Tribelle Combos listed below. My problem is the lack of free time to play R3. In order to succeed in HH1 I will have to play undisturbed for a week or two and that hasn't been possible so far this year.
Anyway, the Matuvu - Tribelle Combos copied from page 315:
1. Start at the top with the Hoodboom and finish the combo with the Tribelle. It goes like this:
The Matuvu Tribelle Combo:
hLDHL|YYYYY|YYYEL|LHMHMu|RRRT
Combo: 9.360
Basic: 2.840
Total: 12.200
Gems in the Warehouse: The Cage, YYY and YYY
Total: 840
Combined: 13.040 points
2. Start with the Cage, kill a Hoodblaster, get to the eight Yellow Gems on the ledge, fall down to kill the Elite Monger and finish with the Tribelle.
The Cage - Matuvu - Tribelle Combo:
yyyyy|yyyyy|yyhly|yyyyy|yyeLLHLLMaHMuRTRR
Combo: 10.510
Basic: 2.390
Total: 12.900
Loose points: The Hoodboom, two Lums and the Door, YYY and YYY
Total: 420
Combined: 13.320 points
The latter is the most profitable, but it's hell to play. It requires immaculate box jumping.
