You can achieve this combination in any battle simply use items or buffing skills like speed up to raise SP without killing enemies, taking damage also increases SP so as you let the battle wage on you should eventually achieve enough SP to use the required moves.

To execute a Special Art you must have two characters who are linked together who can use their EX moves after each other. You can view a list of possible Special Arts in the link below:
Agarest Wiki: Agarest Zero Combination Attacks
The first possible combination attack you should be able to use is 
Grand Stream which is a combination of the following EX Skills:
Gleam Flare (Alice EX 1)
Vortex Howl (Galios EX 2)
iNf3Rn0, Lan
In order to use a special art, you must execute two consecutive (and specific) EX moves. For example, using Sieghart’s LV1 EX Move (Howling Storm) and then Routier’s LV1 EX Move (Aqua Prism) will simply cause Howling Storm to execute followed by Aqua Prism, and NOT gain you the achievement. The earliest Special Art you can do will likely be Alice’s LV1 (Gleam Flare) followed by Galios’ LV2 (Vortex Howl). When these two moves are placed next together in the move list, they will make the move Grand Stream. Even if the combo move “Grand Stream” does not appear, the move will still activate and the move will be added to your Esoterica book afterwards.
Some basic information on EX Moves:
LV1, require 50 SP, cost 18 AP, learned at the start
LV2, require 100 SP, cost 32 AP, learned at lv25
LV3, require 250 SP, cost 50 AP, learned anytime past lv45 by using a Proof of Valor.
